Subject: Improving the definition of <polygon>


For a CAP <polygon> element to be meaningful it needs at least four
point-coordinate pairs (three to enclose a space, and then the last is
required to be the same as the first.)  

I wonder if it might be helpful to make that explicit in the data
dictionary, since occasionally I've seen folks try to represent a point
location as a single-vertex polygon.
