[This comment is not on the updates, but on the base text of #18.]
Sec3.2 says:
For example, an implementation could interpret \X{es-u-co-trad} as
matching a collation grapheme cluster for a traditional Spanish
ordering, or use a switch to change the meaning of \X during some
span of the regular expression.
This usage if \X{something} does not look as being similar to what \X
was defined to mean earlier in this document (an extended grapheme
cluster, and having no parameters). My guesses on what this sentence
was supposed to mean failed completely…
Hope this helps,
