  Yes unless you can put the logic splitting the document in the
stream directly in the I/O handlers, in which case, sure
xmlCreateIOParserCtxt() will work. I didn't checked but try to
make sure you build a SAX2 parser context, not just a SAX1, as SAX2
performs better and handle namespaces directly at the parser level
instead of delegating them to the user's callbacks. See debugSAX2HandlerStruct
xmllint.c around line 1581.
  In general too if you have document with DTDs and entities libxml2
SAX support won't be friendly, but I guess it's not the case.
