I ran into problems with very basic applications of GeoRSS to my data
simply because it does not support multigeometry (or the simpler
versions of these).  Multipolygons happen often, for instance when a
single legal parcel is split by a road, right-of-way, or stream bed.

I don't think that multigeometry should be lumped in with the multiple
geometries problem.  It is a completely different use-case than trying
to refer to multiple locations in a single entry, and does not bring the
same 1:many relationship complexity.  It could be addressed relatively
easily be an expansion of the GML geometry types that GeoRSS already
supports.

I will be somewhat annoyed if GeoRSS ends up only supporting
multigeometry through a complex multiple-entry mechanism.
