Proposed v7 XSD for XRI Resolution 2.0 WD 10

["Drummond Reed" <drummond.reed@cordance.net>]

The proposed XRD schema has been uploaded to:

http://www.oasis-open.org/committees/download.php/17287/draft-XRD-cd02-v7.xs
d

A plain text copy follows below if you want to inspect it directly. The only
change between this and the schema in Editor's Draft 09 was to put the
priority attribute into an attribute group so it could be referenced
uniformly by all the elements that use it (even though it's the only
attribute in this group).

If anyone has any issues, please post ASAP. Otherwise this will be the XRD
schema in Working Draft 10 which will be published shortly.
