The only IMS I ever came across was hardly what I'd call 'extensible' - not
unless you actually *like* taking a whole database down in order to create
or modify a single extra link  ;,)

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.
