"versioning" in wfs 2.0 is pretty lame. Doesn't allow for diffs or anything.
Basically just feature versioned navigation. It all really boils down to the
ResourceId [1] element (equivalent to FeatureId) in filter 1.1. ResourceId
has a "rid" (same as "fid") plus other attributes like version, start/end
date, etc...
We are currently working out the best way to integrate this in on our wfs2
branch as we have to deliver the wfs2 versioning requirements. But as with
many things in WFS 2.0 I don't really see it as very useful. The versioning
extension that Andrea came up with is much better imo. Any work that we do
in geotools we do to directly support versioning i think should be based on
that. Since I think those extensions are rich enough to cover the few lookup
requirements for wfs 2.0.
