[Standards] XEP-0314 Security Labelling in Pubsub

I've been working on adding security labelling to Buddycloud, which is
essentially XEP-0060 (with tweaks).
I've opted to deviate from XEP-0314 for various reasons, but the primary
one being that I think it's much harder than it needs to be to write.
I'll skip over §4.3 for now, since that's essentially shoe-horning an
extension to Disco into the spec; I think we need to reconsider that anyway.
§5.2 shows the pattern I dislike:
<item id='368866411b877c30064a5f62b917cffe' slps:label='seclabel-1'>
The problem with this is that it uses a namespaced attribute to reference a
security label elsewhere in the stanza; this just feels really ugly and
What I'd prefer is that we make it a (negotiated) child of the <item/>. So
that's what I've actually written.
The reasons we didn't go this route were because the <item/> element
contains only one element, the payload. I'm thinking that - with
negotiation - we allow subsequent elements to be metadata (and in this
case, a security label element).
I have a feeling this is how it started out.
Does anyone object to this change? (Or have any comments?)
I'd note in passing that this will likely affect MIX as well.
