Yup.  The reason to use a custom regex package is that the regular
expression language defined by XML schema is similar, but not exactly the

The xerces regex package implements the schema syntax exactly with their "x"
option - until the JDK has schema-compatible regex's builtin, we need to
have our own regex impl.

able to elaborate....
