I'll also note that, to be consistent, this must also mean that
MULTIPOLYGON((0 0, 5 5, 5 0, 0 0), (0 0, 0 5, 5 5, 0 0)) doesn't have
a boundary line at LINESTRING(0 0, 5 5).
Well, that Multipolygon is actually invalid - since MPs can't have
coincident line segments. So the definition *is* consistent!
I'm not sure which one that is.
It's the OGC document 99-049 (the first one you sent)
