Why doesn't XPath 2.0 support word boundaries (\b \B) ?

Because the definition of a word boundary varies from one language to another, and it was felt that regex facilities should be language-neutral.

(Though I'm sure a language-neutral definition in terms of character categories would be possible; but the decision what to include was based on conservative criteria.)
