Re: XLink and X2X

  Hi Graham,

 as precised on the XLink draft, the www-xml-linking-comments@w3.org list
is the right place to provide feedback.
 The last call period for XLink is over but we are still seeking feedback
especially from implementor. I will forward this to the list and I invite
you to discuss those aspects there.

  thanks,

Daniel
