He asks some good questions!

Seems wrong to me. Though I admit I don't see a better way, with the
current set of primitives, to express "this server can't do
case-insensitive sorting". There are at least four possible
approaches: (1) kludge it as he suggests; (2) augment the ZeeRex DTD
to allow an explicit <doesntSupport> statement; (3) specify that in
the absence of a <supports> tag, the client can assume that a facility
is not supported; (4) get him to fix his server so it supports
case-insensitive sorting, then the problem doesn't arise :-)
I can see real drawbacks to all four of these.

So, Rob, will you fix the document?
