Is there any documentation on the syntax used by the RegularExpression

unfortunately.
More specifically my question is if the syntax is the same as that of
Javascript's regular expressions (I've done an exslt:regular-expressions
implementation for Xalan that currently uses boost::regex, but since
Xalan requires Xerces using Xerces' implementation would clearly be more
sensible; however the exslt specification requires Javascript syntax).
Xerces-C's implementation is used to implement regular expression
support in XML Schema, so you could start there. It's also quite close
to the syntax defined by XQuery in the functions and operators:
http://www.w3.org/TR/xquery-operators/#regex-syntax
There is also some documentation from Xerces-J, and Xerces-C's
implementation is a port of the Java code from Xerces-J:
