Hi Kylli,
thanks for sharing. And yes, indeed, your previous attempt was based on an
outdated version of CQL2.
For reference, here is the current schema for it:
https://github.com/opengeospatial/ogcapi-features/blob/master/cql2/standard/schema/cql2.json#L87
The draft standard is also available here:
https://docs.opengeospatial.org/DRAFTS/21-065.html
Mind CQL2 is still being modified, the syntax is still being modified, and
the GeoServer implementation
will likely lag behind until they get to a finalized version.
Cheers
Andrea
