Talk:XRX/XRX Application Server

I don't see that MarkLogic has a free community edition, only a trial version.

I don't really get the message behind the following:

The eXist database is now able to provide a rich set of functions that are only available in other application servers. What remains is the application development standards that would allow a large number of people developing XRX applications to all work together.

Is this statement valid anymore?
