This is most helpful. After thinking about Masatomo Goto's reply I realised
that some of the things I had thought were semantically incorrect were
useful.
I have been thinking that we need something rather like an API - or at
least a guide - for people writing link processor tools. I will try to work
out what is - and what isn't - allowed in the spec and maybe if we meet in
Paris have a discussion.
BTW I think XLink is incredibly powerful and if we can develop abstract
processing machinery will revolutionise a lot of what I and others want to
do. My personal prejudice will be to look at XLink first before other ways
of solving problems of inheritance, relations, networks, etc.
