libxml2 pull parser, xmlTextReader, uses a method named xmlParseChunk() 
in pulling. xmlParseChunk() progressively builds an XML tree.
xmlTextReader uses a chunk size of 512, when parsing chunks. So it is 
kind of progressively builds the tree and lets us walk the tree. Is it a 
good enough pull model for the SOAP engine? As far as I know, Guththila 
is written to pull element by element compared to this.

Let me understand this more clearly. So what you mean is that  we should 
be able to serialize/de-serialize AXIOM to and from any of sting, event 
array, DOM etc. formats.

And given the level of deep platform integration we are talking about, 
it would be of little benefit to use a portable runtime I suppose.
I hope we would be better off to write those platform specific stuff 
focusing on only that platform.
