If they had been concerned about what is a word constituent and what is 
not in a certain language, they wouldnbt have included \w and \W in 
http://www.w3.org/TR/xmlschema-2/#cces

\w is locale-independently defined as:
[#x0000-#x10FFFF]-[\p{P}\p{Z}\p{C}] (all characters except the set of 
"punctuation", "separator" and "other" characters)

So I think \b, defined as either a \w-\W, a \W-\w boundary, the start 
anchor, or the end anchor, is also perfectly well-defined and works as 
expected in most circumstances.
