Check out topic maps, which are in the throes of standardization
by ISO, and which are expressible using extended XLinks or HyTime
links. has a draft or two.

The topic map stuff deals with 6 and 7 only.  The rest of the issues
you raise are handled by other standards, existing and planned:

1. Schema languages.
2. Addressing.  See the HyTime standard for a wealth of generality.
3. Stylesheets.
4. Scripts.
5. Applications; maybe SGML architectures and property sets, too.
                 (again, see HyTime for a general approach)
