latest 1.1 XSDs

["Grosso, Paul" <pgrosso@ptc.com>]

Are the latest DITA 1.1 XSD's those posted on 2006 Sep 5 at
http://www.oasis-open.org/apps/org/workgroup/dita/download.php/20143/dit
a_xsd_1.1b.zip

The latest change date in that set is August 30.  There
are files with no comments and files with comments
saying they are DITA 1.0.1 files.

Some lines in topic.xsd, such as:

 <xs:redefine schemaLocation="topicGrp.xsd">
 
refer to topicGrp.xsd which is no longer in the set of xsd's.

Does anyone have a set of XSD's for DITA 1.1 that are up to date
and really work?
