well, that's different. Do you want to know whether both documents are 
equal, or whether they are identical, i.e. whether both references point
to the same document ?

Hmm, just to check whether we are still talking about the same thing
here: do we agree that there can't be a 'node' type, i.e. just a 
'node_ref'/'node_ptr' ?

Else it would be impossible to make that API a wrapper around libs like
libxml2.
