Could you provide some additional information on how you're 
distinguishing between the different categories?

E.g.:

Is [5] := <A><B/></A> ?
Is [2] := <A/><B/>    ?

I might be sounding pedantic, but in the first case the 
A element is encountered 'before' the B element in a traversal 
of the tree structure of the document. 

Therefore the distinguishing feature between [5] and [2] is that 
an A element is encountered first, and the first B element 
is not within the content of that A element?

Note I'm not making any assumption about what those two elements 
are.
