If this is really needed to be done outside the "standard" set I would say
we did really poorly in designing explain - since this is pretty basic; is
actually one of primary reasons I require explain in my implementation.

So two answers to how I do it - what I really do and what I do in the hope
of one day supporting interoperability...

  What I really do is use "retrievalRecordDetails" - using the fact that
in my set up, for the most part, field tags and attributes tags are the same.
Now given this I use "PerElementDetails" to send:
   - a primary field name
   - recordTag. A number I use as an USE attribute
   - alternate names (e.g. 245, ti, title, mainTitle)
   - generic names

  I also, in an attempt to support clients, do "AttributeSetInfo" - it
can carry an attribute primaryName and number - so I send that. Unfortunately
not alternative and generic names. But think this should be enough for CCL -
though haven't thoroughly understood all you sent yet...
