A while ago now, I posted an article on DSDL. In it I commented that part 8, DSRL, had a lot of problems. The new Project Editor, Francis Cave, has recently posted the first cut at a revised draft of DSRL, and also posted some thoughts from me suggesting some more extensive revisions that could be made.
The posting can be seen in the public archives of dsdl-discuss at http://lists.dsdl.org/dsdl-discuss/2009-12/0002.html. dsdl-discuss is a closed list for members of SC 34/WG 1, however comments are welcome on the public list dsdl-comment 'at' dsdl.org archived at http://lists.dsdl.org/dsdl-comment/.
