This sounds more then a bit weird to me; the suggestion moves quite a bit 
away from the DOM design in requiring the caller to have more knowledge 
about implementation of the dom-library.

From your reply I gather that you intend to develop this API and testing 
it in, for example, kspread.

I don't think that is a good idea as it will take too much time and the 
loading can not test all corner cases of the API.  I suggest you write 
some unit tests that comes with an XML file to test all ideas and corner 
cases in it.
Expanding the tests and xml file(s) as your implementation grows more 
mature.
This requires you write the thing using multiple classes and not one huge 
class so your tests actually can 'look inside' the implementation.

It really is the only way to get this to be a stable library any time 
soon :)
