Doesn't sound as if they mean "capabilities" in the security sense, but we
don't need to let that stop us.

A position paper about the Web Calculus would be a Good Thing (Tyler?) --
as would a paper expressing the disadvantages of generalized policy
frameworks for properties where one-size-fits-all is perfectly sufficient.

For instance:

# Various aspects of a Web service may require description. This includes its
# constraints (e.g., 'You must use HTTP Authentication when accessing this
# service') [...]

Whether a service requires HTTP Authentication is, by definition, determined
by whether I get an error if I try to access it without HTTP Authentication.
Anything else is nothing more than a hint.
