[Standards] A plea for help with Publishing Over XMPP

Good evening. I am developing a journal publishing system with XMPP support. I am experimenting with the commenting system of XEP-0277, and, according to Movim, it seems that I fail to create nodes with appropriate properties. I suppose that I fail, because Movim indicates that comments are closed for posts that I publish. I would be glad for any help. Thank you. Schimon
