Hi Paul,

It seems that the problem is not specific to prov-o, but also applies to 
prov-dm (but phrased differently).

Currently, the prov-dm document requires entities to be identifiable. 
Probably, we even
mean for them to have an identifier!

I came across a similar problem, trying to encode parameters of the 
Provenance Challenge 1 workflow.
I am getting something like:

entity(pc1:a26,[pc1:label="slicer param 

Should the domain specific "pc1:value" attribute become a prov attribute 
for interoperability?
