Maybe the intention of the paragraph above is what Matthew says. But I
don't see it (that GET explain is mandatory). Maybe it should be rewritten.

It helps a bit. But does not change the fact that as things progress SRW
  are a group of related protocols based on XML and CQL which uses
different transports that must be profiled.

IMHO, the explain should be able say all supported transports for the
database/resource (Z39.50 included).

Links in explain (possible?) or HTML?
