A couple of points from the ESO crew.
   * UCD version : by MarcoLeoni. It's crucial to be able to distinguish between UCD version. Even more important, services do not have to use differente UCD version in the same document: this should be made clear in the Rec., thus allowing validation of documents using UCDs.


   * UCD terminator : by MarcoLeoni. It would be very useful to modify the definition to accomodate a semicolon at the end of a UCD. In this way, parsing and searching will be simplified. Further info can be found in the following two emails: http://ivoa.net/forum/ucd/0405/0129.htm and http://ivoa.net/forum/ucd/0405/0130.htm
