Valid only for `<text>` subelements.

The `text` attribute contains the text that should be set on the subelement. If the provided string does not contain any newline characters (`'\n'`), the text is set directly as the content of the `<text>` subelement. Alternatively, if the provided string has multiple lines, each line becomes the content of a `<tspan>` child of the `<text>` subelement.

If you need the text to be automatically wrapped inside the `<text>` subelement, you should use the `textWrap` attribute instead. It can automatically add line breaks into the provided string as necessary, and mark them with newline characters.
