It's not like I absolutely need it, CQL is a new feature in Geoserver, I
can simply tell people, look, you can do amazing things with CQL, but no
FID filter, sorry. It's already a neat pleasure to define things in a
compact and human readable format.
Anyways, a few proposals on how it may look:
* FIDFILTER("fid1", "fid2", ... , "FIDN")
* @id in ("fid1", "fid2", ... , "FIDN")
* @id = "FID1" OR @id = "FID2" OR ... (don't like very much this one)
* @("fid1", "fid2", ... , "FIDN")
Cheers
Andrea
