I am not certain that our current processing model[2], requiring the
node to check that it understands all the mandatory headers before
starting the actual processing, makes the "Incremental
parsing/processing of XMLP messages" usage scenario (S21[3]) possible.

On the other hand, one could argue that a carefully crafted extension
might make this possible (e.g. with some kind of summary of the
upcoming headers, although updating the summary may also prove to be
tricky).
