Comment (by pramsey):

 To complete the thought: had I been looking at the original edge table and
 been thinking "I need to add a directionality flag to the right/left face
 information" I'd have just added two booleans to the end of the edge table
 to flag the directionality. very small, additive-only change.

 I think the goal of "hewing to the standard" kind of falls apart when what
 you are adding (the capability to store rings that include a self-
 intersection in the form of a "spike") is a capability the original
 standard didn't anticipate. I imagine if you brought it to the SQL/MM
 folks they'd say "uh, no, you should only have OGC valid rings
 participating in faces". So you're in uncharted waters, change the edge
 table slightly to sail safely through.
