In addition, why are we debating a relation (i.e., 
<http://www.w3.org/ns/ldp#interaction>) that doesn't even exist in 
<http://www.w3.org/ns/ldp> ? Assuming this is a work-in-progress 
relation, where is the document that actually describes said using RDF?

We are trying to indicate the interaction modality for a specific kind 
of document at an address.

Roughly describe, in haste as:
