 * each a sequence of "identifiers" (defined as a non-empty sequence of ASCII alphanumerical
 * characters and hyphens) separated by dots. The `RELEASE` part may not contain hyphens.
 *
 * Otherwise, this format is identical to SemVer, especially in terms of the comparison algorithm
 * (https://semver.org/#spec-item-11). In other words, this format is intentionally looser than
 * SemVer; in particular:
 *
 * - the "release" part isn't limited to exactly 3 segments (major, minor, patch), but can be
 *   fewer or more;
 * - each segment in the "release" part can be identifiers instead of just numbers (so letters
 *   are also allowed -- although hyphens are not).
 *
 * Any valid SemVer version is a valid Bazel module version. Additionally, two SemVer versions
 * `a` and `b` compare `a < b` iff the same holds when they're compared as Bazel * module versions.
 *
 * The special "empty string" version can also be used, and compares higher than everything else.
 * It signifies that there is a NonRegistryOverride for a module.
