Hi Frank,

Nice write up. This will be a significant enhancement.

Regarding MULTI* support, I assume that you would have to support export 
features from all data sources, like postgis. It is common for the 
shp2pgsql loader to create MULTI objects by default. And while 
shapefiles are seem to be mostly NOT MULTI* by default I almost always 
find a random MULTI* in various files. I'm also wondering if the output 
of geometry processing function using GEOS that are built into mapserver 
will be able to be exported via this WFS writer? If so, then it would 
need to support all geometry types possible from that, which would 
include collections in addition to MULTI*.

I guess this raises these questions in my mind:
Do users need to be able to filter the output based on geometry type? Do 
we need to provide MULTI* dumpers to base type?

Thanks for all your work on this.
