That's what I'm saying, yes. Part of the problem is that both minidom
and 4DOM builders use DOM API most of the time to build the DOM tree -
so they can't do things that couldn't be done through the public API.

In particular, if you look at the minidom implementation, there is
simply no way to create a DocumentType that has a non-empty
internalSubset attribute: you can't pass it to __init__ (because it
accepts no such argument), and you can't modify the resulting
dictionary (because it protects itself agains modification).

Again, if you need such capabilities, it would be best if you
implement them, and contribute your changes.
