I think the term "discovery" is used in several contexts in ICN and it would be good to clarify how it is used in the NRS draft.  I looked in the Terminology draft, and didn't see any definitions there that would help.

Name Discovery: Submit a partial name and some constraints to discovery potentially matching content names.  This is what NDN prefix matching and CCNx Selector Discovery do, though both are only one-at-a-time discovery.

Content Discovery: This is what the draft is talking about, and it uses this term.  The draft seems to consider this a name-based routing to some cache or producer.  

If the authors consider that one could do both name discovery and content discovery via NRS, it would be good to call that out, or to make clear that NRS applies to only one or the other.

Are there any other forms of discovery?
