Some people use the term that way.  I wouldn't.  There's a W3C standard
called DOM, which is a tree.  It's also very suboptimal for Python.
Minidom is based on DOM but tries to make some concessions to Python's
simpler world view.  Many will tell you it's still way too Java-esque.

There are other tree models for XML that have nothing to do with DOM,
including Amara and ElementTree.
