This does not quite work for me, unless you allow a catalog to contain exactly
one collection or exactly one dataset.   Right now the only thredds thing that
can be pointed to is a catalog, with the added provision that a catalog with one
collection is effectively that collection -- I would like to point to datasets
with thredds, which requires either that a catalog can point to a dataset or a
collection, or that you extend collection to be isomorphic to dataset.   The
catalog modification would be preferable.

If you are going to have a base element in service, it is only fair that you
have a suffix element, too.  Please leave the suffix element in.
