Data-base. A 'base' or storage of data. It does not specify the

A database needs a structure. You can't just keep adding crap with
different formats into a repository and call it a database.

And, an XML document does not meet the definition of a hierarchical
database. It's a hierarchy, but not an HDBMS.

Here is someone thinking along the same lines ( though he is approaching it
from extending the idea of XML as a database, not so much the
threaded/multiuse aspect ).

Some interesting stats on performance in Part II:

2) 8) Branched XML - Keywords + IDs as Tags - Grouped Keywords 2.340
