Charles,

Please see comments below:

Regarding #1: You should declare <link> as a global element in the
schema and simply reference it where necessary. If you'd like to hide
the XLink attributes in the instance document, you could also use fixed
attribute values and just include a <link> element in the document where
necessary (this assumes that you will have the same set of XLink
attributes for each <link> element - if not, you could name them
<link1>, <link2>, etc. or with more descriptive names).

Regarding #2: It is unnecessary to declare these. The fact that they are
used within the XLink namespace will cause the XLink processor to
interpret them accordingly.

Kind Regards,
Joe Chiusano
