Sorry if this has been discussed to death before (if so I must have
missed it...).
With subsections available, what about taking advantage of the new
protocol extension and add to the subsection info about the size of the
subsection?
Also, with the size information, would it make sense to specify optional
subsections that the receiver could choose to ignore? Mandatory
subsections are something such that round-trip A->B->A fail unless B
understands the subsection, while optional subsections are such that A
can provide a default. IDE subsections would be optional, for example.
Paolo
