Yes. Neethi is a library to parse/process Policy documents. Thus, making
sure proper policy documents are passed in is important for the methods that
are supposed to actually return a Policy object.
That said, I had thought about adding method like:
PolicyComponent getPolicyFragment(Object)
or similar for parsing subsections of a policy document, but even that may
require the "root" to be a known policy, although that would at least allow
you to manually iterate over the child elements and process one at a time.
Just never got around to that.
