Groups - DITA 1.1 Language Specification -- draft (ditaref-alpha.pdf) uploaded

Proposed additional wording for index-see.

In addition to my earlier email, I realized that
we need to cover the case of multiple index-see
elements for a single index entry.  I assumed it
might make sense to see "see Goldfish, see Carp",
so I decided that is not an error.
