I am going to take a stab at summarizing where I think the definition of a legal appendage is at this point. I believe that the only legal appendages at this point would be a U or T shaped one with the bottom of the U or the top of the T pointing up prior to deployment. As the appendage is deployed the bottom of the U or the top of the T, which in both cases would be the contiguous part, would be the first edge to break the frame perimeter. Does this seem like a reasonable, common sense approach to take?
