Dave Hoffer commented on XERCESJ-955:
-------------------------------------

Yes, I too have schemas defined with this problem.  What is the fix/workaround?  How can I change the schema to that xerces can handle the same functionality?

> [Error] bmecat_new_catalog_1_2.xsd:2952:38: InvalidRegex: Pattern value '([+-]([0-1][0-9]|2[0-3])(:[0-5][0-9]))|Z' is not a valid regular expression. The reported error was: ''-' is an invalid character range. Write '\-'.'.
> Looks like it assumes a range when hitting the '-', but it is actually just a character. Probably needs to check whether '-' is at beginning or and of brackets.
