It would be useful if we could expand upon the existing supported geometry types for filtering OGC WFS services exposed by ArcGIS Server to include multipolygons/multisurface. At the moment I'm working around this by providing the WFS service a convex hull and removing the extra features returned by the service by performing an extra spatial filter client-side. It would be good to be able to make this workflow more efficient by having the server be able to perform the multipolygon filtering.
