[Smith, Adrian]

There actually is an XDBMS.  It predates XML.  This dates back to around
1965/1966.  The database created was titled "IMS" for Information
Management System, it was created by IBM and used an hierarchical model
for the data.  It had all the same characterstics of XML with almost the
exact same set of constructs and shortcomings.

Thanks!
