What capabilities should the analysis server provide via DTD?

[bwilkerson]

We now (or soon will) have the ability to expose services from the analysis server through DTD. We don't currently have any concrete plans to do so beyond what's needed by the Property Editor, but we're interested in understanding which services would be useful to DTD clients in order to inform future planning.

If you have general comments, please add them to this issue. If you have specific requests, please create a sub-issue so that we can track the request separately and have a more focused discussion about it.
