Persistence is done by id.  Since IDs in XBL are non-unique pretty much by definition, and since the XBL anonymous content is not accessible from the DOM, I certainly wouldn't expect this to work.

But in any case, it sounds like a XUL issue, not an XBL one.

yes I know how persist data works with uri and unique id.
but how can be solved problem of persistent data in XUL defined by XBL?
(for example i'm using on several places listing of articles/users/images of our open-source CMS which is defined by .xbl, and users can't setup using this standardized way which columns are enabled/disabled)
btw: sorry for my english

Since this will probably never be fixed, a simple workaround is to put attributes on the xbl instanciated node, and to use xbl:inherits and DOM Mutation Observers to keep attributes synchronized.
This can be very heavy, having a LOT of attributes in your instance.
