review of index* elements [was: DITA 1.1 Language Specification -- draft (ditaref-alpha.pdf) uploaded]

["Grosso, Paul" <pgrosso@ptc.com>]

index-see
---------
The description doesn't make clear when a see becomes 
a see-also and vice versa or whether there are error 
cases and/or when we ignore one in favor of the other.

index-see-also
--------------
Will the "Content reference to..." in this description
actually become a content reference in the next draft?

The description doesn't make clear when a see becomes 
a see-also and vice versa or whether there are error 
cases and/or when we ignore one in favor of the other.

indexterm
---------
In the first bullet point ("In a map..."), there remains
a question ("???") about how to define the maximum
scope of a range specified in a map file.

index-sort-as
-------------
There remains lots of issues about "global sort order" 
using indexterms within the prolog.  For one thing, this
contradicts other decisions we made about what an indexterm 
within the prolog means.  See also my email of July 26:
http://lists.oasis-open.org/archives/dita/200607/msg00076.html
with other questions/issues about sort-as that have 
never been answered.

Furthermore, it isn't clear to me how to use sort-as for 
a multilevel index term.

It is unclear how to handle the "ignore unless a leaf" 
issue for index-sort-as.
