processing-role attribute

Recently we approved adding the new processing-role attribute, with values
of "normal" and "resource-only", to topicref and its specializations. Use
of processing-role="resource-only" indicates that the target is to be used
only as a resource, without appearing in any generated TOC, not linked to,
not generated as part of PDF/XHTML/whatever other output.

We also have a new <keydef> element as a shortcut for defining keys in DITA
1.2. It defaults to toc=no, linking=none, and print=no. So my question is,
should it also default to processing-role=resource-only? This seems
logical, and in fact seems part of the reason we added resource-only, but I
don't think it was called out in the original discussion.
