RE: [xml-dev] Xlink Isn't Dead

["Len Bullard" <cbullard@hiwaay.net>]

Michael Kay stated a list of requirements.  I've not seen them elaborated.

>* flexibility in the management of referential integrity

You may want to start with the 'etc.' and work your way back up the list.

It is my experience that most of what is needed can be done with a
relational database and an implementation of one way links, but that is
implementation, not requirements and such an implementation is
system-dependent regardless of the scale of the solution.

Which is curious on this list.
I feel sure that there is sufficient exposure and experience here to 
define a set of requirements for xlink
and implement them, as was the case with sax.
The need is there (IMHO);  I can't recall that being in doubt?


I guess all that is missing is a David Megginson to take the lead and 
put forward the (a?) proposal.
Bob,  Jirka, Ben, someone else?
