That is the approach I argued for at some point on DC collections.
In the DC CD AP, we are currently using "DC CD AP Usage" (rather than
"DC CD AP Definition"). We do have both a "DC CD AP Usage" and a "DC CD
AP comment", though I regard both as supplementing/annotating the DCMI
definition.

This is what I _want_ to be true, and I've tried to approach DCAPs as
if this is the case.... but I do seem to recall a conversation with Dan
and Charles on top of a skyscraper in Shanghai in which they argued
that "definitions" and "meaning" were _always_ "social" and shifting
and context-sensitive.
At that point I covered my ears and started singing loudly to myself
and clutched my security blanket tightly, least my carefully
constructed world fall apart around me.
