This is an area which we need to flesh out more (and I've argued this
with Ralph in the past). The current CQL is very much based around
textual queries which I've argued against. However, apart from myself
(who need to support audio and music queries) and now ARTISTE there does
not appear to be many sending non-textual queries in Z39.50 (if there
are please shout up!).
