Michael Glavassevich commented on XERCESJ-589:
----------------------------------------------
Sorry, java.util.regex isn't an option here. We cannot use it because it
doesn't support the regular expression language defined by the XML Schema
specification [1]. The one supported by java.util.regex is quite different.
We also cannot use java.util.regex because it was introduced in Java 1.4.
Xerces-J is still built with Java 1.3 (and should be able to run on Java 1.2).
