	I'd lean toward module-level, as long as it's understood that
an implementation can add extra stuff to its module, but builder-level
would also be acceptable.  Note that there isn't that much top-level
stuff required for a DOM module: exception codes, DOMException, the
Node class and its subclasses, NodeList and NamedNodeMap, and 
a createDocument() function.  createDocument is the only thing not
specified by the DOM1 REC, so anyone implementing DOM will have some
version of the above classes and objects.

The warning message we sent the Russians was a calculated ambiguity that would
be clearly understood.
