okay,  the limitation I was thinking of is that XML Schema's regex are
anchored (sort of sick so don't want to go find the spec and hunt up
the correct wording) and XSL-T not
necessarily

The XSLT regex is very much based on the XML Schema one. Quote from XSLT
spec: "The regular expression syntax used by these functions is defined
in terms of the regular expression syntax specified in XML Schema".

The XSLT spec defines a few extensions (like $ and ^ , reluctant
quantifiers, grouping, replacements) and clears a few dark corners of
the XML Schema regex spec (the latter I find notoriously hard to read, btw).
