[mapguide-internals] /branches root directory reserved only for MapGuide?

To revisit an earlier point:

I think the tool should use the same schema as the existing resource being opened unless the user intentionally wants to upgrade the xml to fix something or add missing directives. Maybe this becomes a config setting? The max schema version should be available from each server so Maestro should at least be smart enough to only use a schema that matches that of the server. All the schemas are available so it's only a matter of deciding which one to use unless of course there is some ugly programming issues I can't fathom with the editor only being able to work with the most recent schema.

Would I be wrong in assuming it's possible for the editors to maintain code to match earlier versions of the schema?

I thought about that version issue, and if Maestro requires a version jump why not jump Server and Web tier at the same time? The reverse would apply, that is if we jump server, then the web tier and Maestro would jump as well.  I think that there is an artificial separation that is being maintained between Maestro, server and web tier.

Having a different release cycle introduces problems for the community to try to find the proper versions to use so we should try to get on the same cycle.  I think that patches can be put out whenever, but we should try to have the releases close.

Version compatibility is easy to message if the version numbers are in sync!

Of course there might be logistic problems as to why we don't want to do the above, but I don't know what they are.

Putting Maestro out of sync, to me is the same as making the web tier out of sync with the server.

Ignoring :)

(Maestro is generally backwards-compatible)

Maestro is on a totally different release cycle than MapGuide. I
wouldn't want to see the next+1 version of Maestro not be able to do a
full-version jump (as feature additions justify) just to keep its
version numbering in sync with MapGuide.

We should do a better job of communicating Maestro's version
compatibility though, in the wiki and on the splash screen...
