Null Pointer Exception on enumeration

           Summary: Null Pointer Exception on enumeration
           Product: XMLBeans
           Version: unspecified
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Validator
        AssignedTo: xmlbeans-dev@xml.apache.org
        ReportedBy: toby.h.ferguson@sun.com


Using the validator in v1 I get a null pointer exception when I attempt to
validate an XML instance document against a schema.

I list the terminal session and the contents of the schema (schema.xsd) and the
instance document (valid.xml) in that order below. Each section starts with +++

+++ terminal session
bash$ validate schema.xsd valid.xml
