Draft SSA V0.90 protocol specification

[Doug Tody]

Dear DAL Folks -

The draft SSA V0.90 protocol specification document has been uploaded
to the TWiki and can be found at the following address:

    http://www.ivoa.net/internal/IVOA/InterOpMay2005DAL/ssa-v090.pdf

For reference the most recent spectral data model can be found at

    http://hea-www.harvard.edu/~jcm/vo/docs/spec.html

Pedro: due to lack of time this version does not yet incorporate your
updated specification for the SIDim-related parameters.  We can review
this further in Kyoto.

    - Doug
