Hello People,

I noticed that the W3C spec for HTML does not fully define image map
area tags.  It probably should.  I'm dynamically generating Image map
Areas using JavaScript, and I want to know what is considered 'legal'.
My questions are...

Can image map areas have negative coordinates?  This is desirable when
you want part of a circle as an area.  For example, if you wanted to
create a circle area in the top left corner that only partially covered
the image it would require some negative coordinates.  Is this legal?

I guess the same could also be desired of polygons.  Is it legal for
polygons to have negative coordinates?

Any feedback in the regard would be greatly appreciated.  If you can
think of a place where I would be better to post this question or pursue
the answer, please advise.  Please respond to my email.
