	/**
	 * Creates an instance of the RenderManager.
	 *
	 * Applications or controls must not call the <code>RenderManager</code> constructor on their own
	 * but should use the {@link sap.ui.core.Core#createRenderManager sap.ui.getCore().createRenderManager()}
	 * method to create an instance for their exclusive use.
	 *
	 * @class A class that handles the rendering of controls.
	 *
	 * For the default rendering task of UI5, a shared RenderManager is created and owned by <code>sap.ui.core.Core</code>.
	 * Controls or other code that want to render controls outside the default rendering task
	 * can create a private instance of RenderManager by calling the
	 * {@link sap.ui.core.Core#createRenderManager sap.ui.getCore().createRenderManager()} method.
	 * When such a private instance is no longer needed, it should be {@link #destroy destroyed}.
	 *
	 * Control renderers only have access to a subset of the public and protected instance methods of
	 * this class. The instance methods {@link #flush}, {@link #render} and {@link #destroy} are not part
	 * of that subset and are reserved to the owner of the corresponding RenderManager instance.
	 * Renderers will use the provided methods to create their HTML output. The RenderManager will
	 * collect the HTML output and inject the final HTML DOM at the desired location.
	 *
	 *
	 * <h3>Renderers</h3>
	 * When the {@link #renderControl} method of the RenderManager is invoked, it will retrieve
	 * the default renderer for that control. By convention, the default renderer is implemented in its
	 * own namespace (static class) which matches the name of the control's class with the additional
	 * suffix 'Renderer'. So for a control <code>sap.m.Input</code> the default renderer will be searched
	 * for under the global name <code>sap.m.Input<i>Renderer</i></code>.
	 *
	 * <h3>In-place DOM patching</h3>
	 * As of 1.67, <code>RenderManager</code> provides a set of new APIs to describe the structure of the DOM that can be used by the control renderers.
	 *
	 * <pre>
	 *
	 *   myButtonRenderer.render = function(rm, oButton) {
	 *
	 *       rm.openStart("button", oButton);
	 *       rm.attr("tabindex", 1);
	 *       rm.class("myButton");
	 *       rm.style("width", oButton.getWidth());
	 *       rm.openEnd();
	 *           rm.text(oButton.getText());
	 *       rm.close("button");
	 *
	 *   };
	 *
	 * </pre>
	 *
	 * By default, when the control is invalidated (e.g. a property is changed, an aggregation is removed, or an
	 * association is added), it will be registered for re-rendering. During the (re)rendering, the <code>render</code>
	 * method of the control renderer is executed via a specified <code>RenderManager</code> interface and the control
	 * instance.
	 *
	 * Traditional string-based rendering creates a new HTML structure of the control in every rendering cycle and removes
	 * the existing control DOM structure from the DOM tree.
	 *
	 * The set of new semantic <code>RenderManager</code> APIs lets us understand the structure of the DOM, walk along the
	 * live DOM tree, and figure out changes as new APIs are called. If there is a change, then <code>RenderManager</code>
	 * patches only the required parts of the live DOM tree. This allows control developers to remove their DOM-related
	 * custom setters.
	 *
	 * <b>Note:</b> To enable the new in-place rendering technology, the <code>apiVersion</code> property of the control
	 * renderer must be set to <code>2</code>. This property is not inherited by subclass renderers. It has to be set
	 * anew by each subclass to assure that the extended contract between framework and renderer is fulfilled (see next
	 * paragraph).
	 *
	 * <pre>
	 *
	 *   var myButtonRenderer = {
	 *       apiVersion: 2    // enable in-place DOM patching
	 *   };
	 *
	 *   myButtonRenderer.render = function(rm, oButton) {
	 *
	 *       rm.openStart("button", oButton);
	 *       ...
	 *       ...
	 *       rm.close("button");
	 *
	 *   };
	 *
	 * </pre>
	 *
	 * <h3>Contract for Renderer.apiVersion 2</h3>
	 * To allow a more efficient in-place DOM patching and to ensure the compatibility of the control, the following
	 * prerequisites must be fulfilled for the controls using the new rendering technology:
	 *
	 * <ul>
	 * <li>Legacy control renderers must be migrated to the new semantic renderer API:
	 *     {@link sap.ui.core.RenderManager#openStart openStart},
	 *     {@link sap.ui.core.RenderManager#voidStart voidStart},
	 *     {@link sap.ui.core.RenderManager#style style},
	 *     {@link sap.ui.core.RenderManager#class class},
	 *     {@link sap.ui.core.RenderManager#attr attr},
	 *     {@link sap.ui.core.RenderManager#openEnd openEnd},
	 *     {@link sap.ui.core.RenderManager#voidEnd voidEnd},
	 *     {@link sap.ui.core.RenderManager#text text},
	 *     {@link sap.ui.core.RenderManager#unsafeHtml unsafeHtml},
	 *     {@link sap.ui.core.RenderManager#icon icon},
	 *     {@link sap.ui.core.RenderManager#accessibilityState accessibilityState},
	 *     {@link sap.ui.core.RenderManager#renderControl renderControl},
	 *     {@link sap.ui.core.RenderManager#cleanupControlWithoutRendering cleanupControlWithoutRendering}
	 * </li>
	 * <li>During the migration, restrictions that are defined in the API documentation of those methods must be taken
	 *     into account, e.g. tag and attribute names must be set in their canonical form.</li>
	 * <li>Fault tolerance of HTML5 markup is not applicable for the new semantic rendering API, e.g. except void tags,
	 *     all tags must be closed; duplicate attributes within one HTML element must not exist.</li>
	 * <li>Existing control DOM structure will not be removed from the DOM tree; therefore all custom events, including
	 *     the ones that are registered with jQuery, must be de-registered correctly at the <code>onBeforeRendering</code>
	 *     and <code>exit</code> hooks.</li>
	 * <li>Classes and attribute names must not be escaped.</li>
	 * <li>Styles should be validated via types (e.g. <code>sap.ui.core.CSSSize</code>). But this might not be sufficient
	 *     in all cases, e.g. validated URL values can contain harmful content; in this case
	 *     {@link module:sap/base/security/encodeCSS encodeCSS} can be used.</li>
	 * <li>To allow a more efficient DOM update, second parameter of the {@link sap.ui.core.RenderManager#openStart openStart}
	 *     or {@link sap.ui.core.RenderManager#voidStart voidStart} methods must be used to identify elements, e.g. use
	 *     <code>rm.openStart("div", oControl.getId() + "-suffix");</code> instead of
	 *     <code>rm.openStart("div").attr("id", oControl.getId() + "-suffix");</code></li>
	 * <li>Controls that listen to the <code>focusin</code> event must double check their focus handling. Since DOM nodes
	 *     are not removed and only reused, the <code>focusin</code> event might not be fired during re-rendering.</li>
	 * </ul>
	 *

		/**
		 * Cleans up the rendering state of the given control without rendering it.
		 *
		 * A control is responsible for the rendering of all its child controls.
		 * But in some cases it makes sense that a control only renders a subset of its children
		 * based on some criterion. For example, a typical carousel control might, for performance
		 * reasons, only render the currently visible children (and maybe some child before and
		 * after the visible area to facilitate slide-in / slide-out animations), but not all children.
		 * This leads to situations where a child had been rendered before, but shouldn't be rendered
		 * anymore after an update of the carousel's position. The DOM related state of that child then
		 * must be cleaned up correctly, e.g. by de-registering resize handlers or native event handlers.
		 * <code>cleanupControlWithoutRendering</code> helps with that task by triggering the same
		 * activities that the normal rendering triggers before the rendering of a control
		 * (e.g. it fires the <code>BeforeRendering</code> event). It just doesn't call the renderer
		 * and the control will not receive an <code>AfterRendering</code> event.
		 *
		 * The following example shows how <code>renderControl</code> and <code>cleanupControlWithoutRendering</code>
		 * should be used:
		 *
		 * <pre>
		 *   CarouselRenderer.render = function(rm, oCarousel){
		 *
		 *     ...
		 *
		 *     oCarousel.getPages().forEach( function( oPage ) {
		 *        if ( oCarousel.isPageToBeRendered( oPage ) ) {
		 *           rm.renderControl( oPage ); // onBeforeRendering, render, later onAfterRendering
		 *        } else {
		 *           rm.cleanupControlWithoutRendering( oPage ); // onBeforeRendering
		 *        }
		 *     });
		 *
		 *     ...
		 *
		 *   };
		 * </pre>
		 *
		 * <h3>DOM Removal</h3>
		 * The method does not remove the DOM of the given control. The caller of this method has
		 * to take care to remove it at some later point in time. It should indeed be <i>later</i>,
		 * not <i>before</i> as the <code>onBeforeRendering</code> hook of the control might need
		 * access to the old DOM for a proper cleanup.
		 *
		 * For parents which are rendered with the normal mechanism as shown in the example above,
		 * the removal of the old child DOM is guaranteed. The whole DOM of the parent control
		 * (including the DOM of the no longer rendered child) will be replaced with new DOM (no
		 * longer containing the child) when the rendering cycle finishes.
		 *
		 * <b>Note:</b>: the functionality of this method is different from the default handling for
		 * invisible controls (controls with <code>visible == false</code>). The standard rendering
		 * for invisible controls still renders a placeholder DOM. This allows re-rendering of the
		 * invisible control once it becomes visible again without a need to render its parent, too.
		 * Children that are cleaned up with this method here, are supposed to have no more DOM at all.
		 * Rendering them later on therefore requires an involvement (typically: a rendering) of
		 * their parent.
		 *
		 * @param {sap.ui.core.Control} oControl Control that should be cleaned up

	/**
	 * Collects accessibility related attributes for an <code>Element</code> and renders them as part of
	 * the currently rendered DOM element.
	 *
	 * See the WAI-ARIA specification for a general description of the accessibility related attributes.
	 * Attributes are only rendered when the accessibility feature is activated in the UI5 runtime configuration.
	 *
	 * The values for the attributes are collected from the following sources (last one wins):
	 * <ol>
	 * <li>from the properties and associations of the given <code>oElement</code>, using a heuristic mapping
	 *     (described below)</li>
	 * <li>from the <code>mProps</code> parameter, as provided by the caller</li>
	 * <li>from the parent of the given <code>oElement</code>, if it has a parent and if the parent implements
	 *     the method {@link sap.ui.core.Element#enhanceAccessibilityState enhanceAccessibilityState}</li>
	 * </ol>
	 * If no <code>oElement</code> is given, only <code>mProps</code> will be taken into account.
	 *
	 *
	 * <h3>Heuristic Mapping</h3>
	 * The following mapping from properties/values to ARIA attributes is used (if the element does have such properties):
	 * <ul>
	 * <li><code>editable===false</code> => <code>aria-readonly="true"</code></li>
	 * <li><code>enabled===false</code> => <code>aria-disabled="true"</code></li>
	 * <li><code>visible===false</code> => <code>aria-hidden="true"</code></li>
	 * <li><code>required===true</code> => <code>aria-required="true"</code></li>
	 * <li><code>selected===true</code> => <code>aria-selected="true"</code></li>
	 * <li><code>checked===true</code> => <code>aria-checked="true"</code></li>
	 * </ul>
	 *
	 * In case of the <code>required</code> property, all label controls which reference the given element
	 * in their <code>labelFor</code> relation are additionally taken into account when determining the
	 * value for the <code>aria-required</code> attribute.
	 *
	 * Additionally, the associations <code>ariaDescribedBy</code> and <code>ariaLabelledBy</code> are used to
	 * determine the lists of IDS for the ARIA attributes <code>aria-describedby</code> and
	 * <code>aria-labelledby</code>.
	 *
	 * Label controls that reference the given element in their <code>labelFor</code> relation are automatically
	 * added to the <code>aria-labelledby</code> attributes.
	 *
	 * Note: This function is only a heuristic of a control property to ARIA attribute mapping. Control developers
	 * have to check whether it fulfills their requirements. In case of problems (for example the RadioButton has a
	 * <code>selected</code> property but must provide an <code>aria-checked</code> attribute) the auto-generated
	 * result of this function can be influenced via the parameter <code>mProps</code> as described below.
	 *
	 * The parameter <code>mProps</code> can be used to either provide additional attributes which should be rendered
	 * and/or to avoid the automatic generation of single ARIA attributes. The 'aria-' prefix will be prepended
	 * automatically to the keys (Exception: Attribute <code>role</code> does not get the prefix 'aria-').
	 *
	 *
	 * Examples:<br>
	 * <code>{hidden : true}</code> results in <code>aria-hidden="true"</code> independent of the presence or
	 * absence of the visibility property.<br>
	 * <code>{hidden : null}</code> ensures that no <code>aria-hidden</code> attribute is written independent
	 * of the presence or absence of the visibility property.<br>
	 *
	 * The function behaves in the same way for the associations <code>ariaDescribedBy</code> and <code>ariaLabelledBy</code>.
	 * To append additional values to the auto-generated <code>aria-describedby</code> and <code>aria-labelledby</code>
	 * attributes, the following format can be used:
	 * <pre>
	 *   {describedby : {value: "id1 id2", append: true}} =>  aria-describedby = "ida idb id1 id2"
	 * </pre>
	 * (assuming that "ida idb" is the auto-generated part based on the association <code>ariaDescribedBy</code>).
	 *
	 * @param {sap.ui.core.Element}
	 *            [oElement] The <code>Element</code> whose accessibility state should be rendered
	 * @param {object}
	 *            [mProps] A map of additional properties that should be added or changed.
