[xml-dev] Companies that have switched from RDBMS to pure XML database?

It would be helpful if you could be more explicit about the FROM
database.

Relational purists will argue there has never been an implementation of
a relational DBMS. So it's probably best to consider SQL databases, but
there's a bifurcation of the SQL DBMS world:

1. Some SQL platforms do not support an XML data type so it's necessary
to shred an XML document or store it as a CLOB column (with the XML in
its native format).
2. Other SQL products have implemented an XML data type and/or a hybrid
storage engine that stores XML in its native format.

The switch getting the most publicity these days is from SQL platforms
to distributed key-value stores, not to XML data stores.
