I am a bit confused about the intent of SIA v2.  In the abstract, the
draft talks about data cubes, but the text does not any general
support for selection that, for example, AccessData has.

  http://wiki.ivoa.net/internal/IVOA/AccessData/WD-AccessData-1.0-20140312.pdf

To be precise, AccessData provides a way to select a slice in an
arbitrary coordinate (e.g. redshift) with the COORD parameter.  I do
not see anything comparable in SIA v2.

I am fine with SIA v2 not supporting this kind of thing, but I just
wanted to clarify the intent.

Also, SIA v1 had support for mosaic services.  I have been looking
through the mailing list, but I have not found a definitive answer.
Is support for mosaic services a non-goal for SIA v2?  If so, perhaps
that should be mentioned in the introduction?

Thanks,
