At first I thought, that sounds reasonable to me. Then I realised it
means that anyone who wants to add a (namespaced) extension to an
Explain-- record is only allowed to do so when that record is
requested with an element-set name other than "f". That I'm not so
keen on. (Also, isn't there at least the implication in the standard
that "f" returns all available elements?)

Ah, OK. So it had namespaces, but not the same namespaces that XML
has. So if any server were to return a record with a namespaced
element or attribute, it would have to decide what sort of record it
was: XML or SGML -- a decision which sort of has no impact with the
records we've been discussing up till now. Awkward. I'm half
inclined to say (and I know you won't like this, Rob), badgers to SGML
-- let's just jump right into XML camp and have done.
BTW., just had another name idea, which I thought I may as well chuck
into the mix. "ExplainAgain". I think it does OK on the Tin, Google
and Pronouncability tests. My reservation would be that it's sort of
