You must have made a typo and meant a different word for the first time
you used syntax (in the second line).  Otherwise, sorry, but I can't
make any sense *at all* of what this might mean.

I disagree, for the reasons listed in my original note.

I'll re-emphasize that the Infoset is completely devoid of syntax -- the
first appearance of "<" is in the non-normative appendix C.  As the very
first line of the Infoset CR says, "it defines an abstract data set." 
But if you're defining a network protocol, then you MUST define syntax;.
You must MAKE EXPLICIT the bits on the wire.

Oh, nonsense.

The XML spec makes it clear.

Actually, your example should help make it clear why -- for a network
protocol -- the Infoset is a lose: it doesn't answer that question.  It
doesn't even come close.
