IMH (if oft-repeated) opinion, 'parsing (syntax)' is the inherent mechanism of
XML for 'interact[ing] with the data structure'. The data structure is
discovered in the parse of the instance. If that structure as discovered does
not correspond to some pre-ordained model or abstraction, then this instance is
not valid against that model. Nevertheless this instance--allowing only that it
is well-formed--is XML and, I would argue, the correct and most XML-compliant
mechanism for extending processing capabilities designed to operate upon XML
instances.
