Updating TC211 Model
====================
To update the TC211 model, download the new version (see section below), rename/move it "ISO-TC211-Model.xml" in this directory, and check it in.  Then edit this document to indicate the current version.  This model uses a version-independent file name to make it easier for updates to this model to be imported seamlessly. This README was created to track the version that is currently checked in.
