Hi,
No, you can't add random attributes like this in any XMPP protocol
element and expect it to work.
For storing feed meta data on nodes, there are two options:
1. Having a special item to hold it. See section 5 of XEP-0277.
2. Add meta data on the pubsub node's configuration. Some fields
already exist to cover information from the feed level meta data. If
there's no direct match, you can use Clark Notation to namespace
custom fields (see XEP-0068).
I also want to call out a special mention of a deferred XEP to store
XML in a form field, which references the exact use case: XEP-0315.
