I can now answer my own questions:Is it possible to define multiple data schemas over the same FDA table?A: Yes.  As many as you like.Returning different subsets of data for a given schema:A: Code as follows in the schema xml: <sysFilter><condition expr="@field in ('val1','val2')"></sysFilter>

I am trying to understand whether it is possible to define multiple data schemas over the same FDA table, but each one returning a different subset of data.If this is possible, how can it be achieved (what are the xml directives to use, and any limitations or traps to be aware of).Thank you.
