Good point.

But then we do need to ensure that there are no sub-protocol name
clashes.     My suggestion is to use real URLs as sub-protocol
names, like DTDs

Also I think a single sub protocol name is not very flexible.
You might want to combine multiple sub protocols - one for
gzip, one for orderly close etc.   or is that a subprotocol
that supports optional features?
