Jody Garnett reopened GEOS-434:
-------------------------------

Assign To: dblasby (was: Gabriel Roldán)

Suel we seem to have a miss understanding, I voted -1 because geotools was not ready (did not have a convention in place) to support patches that extended functionality defined by a standard. -1 means not yet but I will help, and in response to your patch we have set up geotools to allow for this.

I would love to see your patch applied to 2.2.x and included in a future geoserver release. The part we needed to do is completed and I would now vote +1. (The only negative vote is +0).
