What do you think of this picture?  Does this clarify or just further confuse?

Caption:  Though the focus so far has been on two level recursion (Dataset search to Granule Search), this need not be the case. This shows a 3 level recursion, beginning with a search for search providers (or engines) satisfying user criteria (e.g., searchTerms="ozone").  Each step in the recursion returns links to OpenSearch Description documents, which in turn inform the client on how to execute the next level search, until the lowest level, where the return consists of links to actual data of interest.
