Regular Expression and XML Sample Builder

I am generating a sample XML document from a schema. One of the elements in the schema contains a regular expression pattern "30\d{6}|60\d{6}". Yet when I generate an xml-example no numbers are used but characters instead.
The outcome should have been an eight digit number starting with "30" or "60"

The XML sample generator is designed to build a skeletal XML document, a starting point for you to plug your own data into. On the whole these documents will be valid. But regular expressions are very difficult to parse and build valid expressions from, the current version does not fully support the generation of XML from an XML Schema containing regular expressions.

If there are any other areas the XML sample builder is failing on, please let us know and we will endeavor to solve the problem.
