You mean power as in "quantity measured in Watts"?

Assuming that's the case, I'd tend to view it as a quality-of-service
(i.e. non-functional) requirement, and also one that is out of our
current scope. As such, you'd probably want to use a custom extension
term to describe the power requirements, and something like WS-Agreement
to drive the enforcement. (OTOH, I don't have access to any sort of
system at the moment which could support such a term anyway; all our
production kit doesn't know anything about its power consumption.)

Hope this helps (a little).

Donal.
