(b) they wanted to exclude anything that didn't make sense in an

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.
