About descriptions of policies. In section 4.2, the author just gave a high-level descriptions of the policies. I'm curious about how to convert this high-level description into the more specific form described in the beginning of this section?

One would think that after expending the effort to formalize their approach and including an example, that the authors would express the policies in a specific language so the reader could use it to follow the system description. In their defense: a) the specific types of "contextual predicates" are not of concern to this approach: the policy applicability is handled by which ever "black box" is chosen to evaluate them (the "more specific form" you mention handles the contextual predicates independent of the specifics), and b) the path expressions and boolean expressions commonly recognized.warning.pngString representation One would think that after expending the e […] d boolean expressions commonly recognized. is too long.
