um... how can I explain it better than the words themselves?  I mean 
that the structure of the object is predictable; the ontology dictates 
the structure.  Therefore, I can design a parser that will reach into 
the correct structural position in the XML and extract the content at 
that position.

The two are identical - that is the whole point!  The *structure* of a 
"specialized" DNA sequence compared to a GenericSequence is identical! 
 therefore you look for exactly the same the same tags/document 
structure  in both cases.  The only tag that has changed is the 
"primary" tag of the object - the one at the root level of the XML document.

To see an example, send a request to my GenbankCompleteSequenceRetrieve 
service.
