I'm happy with postponing it, either moving it to an appendix or a separate, 
linked document.

Either way, it could also link to a more discursive WG Note that surveys the 
current options.  (There's material out there already so it might be 
sufficient to just link to it after reviewing it - and then there's service 
description or different service endpoints.)

I would like to see the keyword reserved and the current syntax maintained as 
it is already out there.  I'm neutral as to adding the extra argument as an 
optional part or the syntax.  ARQ would support it if it were added.

[[Graham's proposal only captures the "set of known algorithms" usage, not the 
case where what is returned is influenced by the data itself (e.g. find a 
resource of type book, so return the ISBN number).  But my feeling is that the 
"set of known algorithms" is a common usage.]]
