I have been thinking about killer apps for out of band signalling to try 
to answer to this question and, here are some proposals:

- Addition of PSVI information embedded in the instance documents [1].
- Meta data. A Dublin Core variant expressed as PIs would be
   immediatly usable everywhere (even in vocabularies having made no
   provision for any type of meta data).
- And even a variant of RDDL using PIs instead of XLink would have
   been cool and less verbose (RDLL elements are truly "Processing

I am begining to wonder if out band signalling -using PIs or not- hasn't 
a big role to play for the Semantic Web :) !


See you in Seattle.
