Well, I'm certainly not an XML expert, but here is what I've read from
the specs:

-----------

[1]   	document	   ::=   	prolog element Misc*

 	Misc	   ::=   	Comment | PI | S

      [Definition: There is exactly one element, called the root, or document
element, no part of which appears in the content of any other element.] For all
other elements, if the start-tag is in the content of another element, the
end-tag is in the content of the same element. More simply stated, the
elements, delimited by start- and end-tags, nest properly within each other.

-----------

So, if there is exactly one root element and if the client does not send
any Misc, I guess that detecting the end of the root element should
indicate that I received the whole request, right? Would redefining
endElementSAXFunc for such a purpose do the trick?
Or, what am I not understanding?

Thanks.
