This is my attempt to respond to ACTION-92.

This is hard to do without a complete formal description of what 
contextualization actually means.

I did reply [1] to Tim's comment, and the reference to the example in the wiki. 
  I would adjust my earlier comment to say something like this:  I cannot see 
how contextualization can be anything but vacuous without violating RDF 
semantics; i.e. how it actually expresses anything that cannot be expressed 
without it.

I've studied the description of contextualization in DM 
(http://dvcs.w3.org/hg/prov/raw-file/default/model/prov-dm.html#term-contextualization), 
and when I dig in to it I find I can't make any sense of what it is saying.

As it stands, the notion of context is undefined, so I am unable to interpret 
statements like "A bundle's descriptions provide a context in which to interpret 
an entity in a domain-specific manner".  What is this "context"?  When I look to 
the definition of "bundle", I see "A bundle is a named set of provenance 
descriptions ...".  There's nothing here about defining or providing a 
"context".  So this notion of context is being introduced without any grounding 
or basis for understanding what it means.
