Well yours seems a deeper mystery but my complaint is that the docs (and
comments in the RL code) say that if you want a border you can pass in
Border='[1 1 1]'. But _annFormat as written just blats that parameter :

D["Border"] = PDFArray(border)

With no prior attempt to do something like :

border = RescueFromParameter(D["Border"])

And that's what my fix attempted to do. But if we just need to change
the docs to say "In order to draw a border around your links you need
to..." then fine. 

I can change my code no problem but the code and the
documentation/comments in RL are out of whack and I think that needs to
be addressed.

Thanks.
