Actually, the DOM can be mapped into a language in a manner that does
not follow directly from the IDL and CORBA specs. That's why there is a
formally defined java binding rather than just a reference to the IDL
specs. Historically, though, 4DOM was really a CORBA tool so it really
needed to follow the specs.
I would vote for losing the leading underscore.

I think it is safe to say that a binding should not require a particular
underlying data structure but Python allows the use of a.b syntax even
when the surface structure is wildly different than the underlying data
structure. I'm preaching to the choir as you are the world leader in
abuse of the dot notation. :)
Visual Basic and ECMAScript (the latter is actually specified) also use
dot notation for what could conceptually be a method invocation.
