The reason that \b isn't in the XPath regular expression dialect is that its
meaning is very sensitive to the conventions of the natural language that
you're using. This restriction is in the W3C spec, not in Saxon.

A lot depends how clever you want to be. I would think you'd get a 95%
success rate by using

tokenize($in, '[\.\?!]\s+')

but in my experience it's tricky knowing what to do about characters such as
")", '"', or em dash that might appear immediately after a full stop.
