Digital signature usually suffice. Basically any "secure mechanism" 
would usually be OK. In European Union VAT directive there is talk about 
secure EDI with basically an TPA + established electronic communication 
practices.

Not really, im discussing "aspects" and not where to put/store/capture 
an expression of Capability.

No, I mean the Capacity aspect (instance-level) as in how many pizzas an 
owen (pizza making capability) can handle per hour.
The relevance of the Capacity aspect may be viewed in the light of 
European principles of Contract law:
"Article 2:201 "(3) A proposal to supply goods or services at stated 
prices made by a professional supplier in a public advertisement or a 
catalogue, or by a display of goods, is presumed to be an offer to sell 
or supply at that price until the stock of goods, or the supplier's 
capacity to supply the service, is exhausted."

"Article 4:101: Matters not Covered
This chapter does not deal with invalidity arising from illegality, 
immorality or lack of capacity."

Permission, Authorization, Enactment-specification and Participation are 
other relationships between an Actor/party and behavior such a BPSS 
(which is a emergent collaborative behavior, ie.e composed of actors 
sendig and receiving).
