Sounds great !
My email suggested doing "class name.field" as well as converters. I think
you could get away with making that a converter for the same effect.
Give it a go.

I've coded this up, here is the patch:
https://github.com/aaime/geotools/commit/23b41be622bc01e6a84b9ba93fde99ef735292cd
Basically I'm using converters to convert from string to object as you
suggested.
Two things to notice:
- I ported back a enum converter from GeoServer that I wrote myself (so I
have rights on relicensing to LGPL)
- I had to make sure the types of the params are never reported as being
primitives (e.g boolean.class)
as that breaks converters solid, and due to the usage of generics it's
actually not possible to fix
the converters itself (there is no way to cast a primitive to a generic
type)
One thing that we might want to add is a converter that takes either a
name, which is supposed
to be the name a constant in the target class (e.g., Filter.INCLUDE), to
grab values from constants,
and also support the "this.is.my.package.Class#constant" syntax to fetch
constant values from
converters itself.
Just an idea.
Ok to commit?
Cheers
Andrea
