Log:
Addressing JIRA Issue #618:
http://issues.apache.org/jira/browse/XERCESJ-618

Adding a method for retrieving the content spec index for an element declaration.
This has been requested by several members of the community over the years since
there is no other way to get this information aside from hacking up a local copy
of the class.
