The Unicode Technical Committee has posted a new issue for public review and comment. Details are on the following web page:

Review periods for the new items close on July 25, 2011.

Please see the page for links to discussion and relevant documents. Briefly, the new issue is:

184 Proposed Update UTS #37, Unicode Ideographic Variation Database (IVD)

This update to UTS #37 will clarify how Ideographic Variation Sequences (IVSes) can be shared across IVD collections, that no IVD collection has special status, and that implementers can support any subset of the registered IVSes.

It will further amend the specification to allow duplicate sequence identifiers within an IVD collection under particular circumstances, and to allow registrants to supply multiple representative glyphs for IVSes in their IVD collections. Finally, the registration procedures will be strengthened to require registrants to supply representative glyphs for registered IVSes and to supply a data file as part of a submission.
