TSAP was essentially a prototype for the current SSAP for theory
data; it just needs to be updated. It is still ahead of the other
apps in this area though. The general problem here is not theory
data specifically, but that a fully general application should be
able to support service specific parameters, and dynamically query
these and permit the user to specify arbitrary queries. This allows
a standard mechanism to be extended to do many things, including
(but not limited to) control params for a theoretical model.

Yes, of course.

Yes. I am sure this will be the case soon, but it does not hurt
to encourage this, and bug those responsible for the major apps to
support this capability.
