I'm happy with 1-ended links (see for example their use in Robin
Milner's Bigraphs), but I thought that's what extended links were for:
they let you do pretty much anything, whereas simple links are meant
to be just that: simple.  That is, one local anchor, one remote
anchor.  No more and, I thought, no less. . .
