Re: [ADMIN] Minutes of 1 September 09 telecon

For the records: There were some small changes on DTB and some 
discussions about it:

1) http://lists.w3.org/Archives/Public/public-rif-wg/2009Aug/0002.html
2) http://lists.w3.org/Archives/Public/public-rif-wg/2009Aug/0011.html
3) I think I asked in the last TC whether we can/shall change the 
non-uniformity of the list-functions in DTB, which have a different format
(informal mappings only) to all the other functions and predicates in 
DTB. I could try to tackle that, but not before two weeks from now.

With the resolution to go to CR, should I consider these resolved/accepted?

p.s.: Belated regrets due to arrival of our child ;-).
