From what I read, the 11 mm rope has a breaking strength of 6,000 lbf. The way that I interpret the rules, this is an adequate rope for access. I doubt that you're using it as a climbing line.
All of that said, you should write to Jim Skiera or Bruce Smith to get a final ruling. Bruce lurks here, HI RRUCE , so he might chime in.
Somewhere in the rules it refers to ropes needing to be made for the arbo industry or approved by the manufacturer for our industry. I think that is a rule that could use a review. Rather than set an industry specific standard, set a performance or specification standard. Since there aren't any accessory cords, that I know of, designed for arbos, this might, by a strict interpretation of the rules, make all cords suspicious. The innovations that have come from allowing a variety of cords has changed climbing. Think of what it might mean if this same idea is allowed for climbing lines.
