OK, this is more precise, which is good; but this definition of the
meaning of "DCX" will not, of course, because a part of Z39.50 itself:
it's merely profiling, so you'll put that prose in your profile.  But
you were _always_ at liberty to write your own profile that gives its
own meaning to any element-set name you chose.  So what has changed
here?  What have we given you that you didn't already have?

So I think your problem remains just as bad as it was before: your
client can ask for XML records with the "element-set name" DCX, but
unless my server's signed up to your profile, it can do what it wants
in response.  Just as it could before we even had this discussion.

So is that it?  The answer to all your problems was: profile them.
