[mapserver-dev] call for vote on rfc 48

[Steve Lime]

I worked backwards through the thread, sorry. Just wanted to note that the shortcut
notation would address Paul's concerns about [geom] in the short term.

The square brackets associate something with a shape attribute. I consider the
geometry an attribute which is why [geom] (or [shape] or [geometry], pick one)
made sense to me.  

For now, for the unary operations supported in this RFC we could adopt a shortcut
notation and omit the ([geom]). We'd re-introduce that notation if we decide to take
things further. So for now you'd have:

  GEOMETRYTRANSFORM BBOX

and in the future we could support that and:

  GEOMETRYTRANSFORM BBOX([geom])

I'd favor the shortcuts for the initial implementation.

hmm, yes I see I missed some out. will correct.

Steve was against that:
"
- syntax should use [geom] instead of plain geom in keeping with
expression syntax
"

I have no preference over one or the other.
