Gavin,
filter complex features by referencing xpath properties in the output.
The client never needs to know about the source tables. app-schema
converts the client filter into filters against the source tables, or
efficient SQL join queries if joining is used.
The cql_filter vendor parameter works fine for top-level properties like
gml:name but I can find no way of encoding xpaths because "/" and "@"
are invalid and not recognised as part of the property selector. In
these cases you should be able to use filter (OGC Filter XML) rather
than cql_filter.
Kind regards,
Ben.

Hi all,
How would one use a CQL_Filter parameter in a WFS request to filter the
results given by an app schema mapped complex feature using feature
chaining. The way I understand it, CQL_Filter operates using a WHERE
statement in a CQL query but how does that work when each (linked) mapping
file may be accessing a different table? Does the filter get applied to the
top level mapping file? I haven't been able to make it work at all. Perhaps
I'm totally misunderstanding it though.
