A policy from the W3C ODRL examples. The table gives the source and what the policy shows, in the source's words.

Source	What it shows
model#constraint-action	Example Use Case: In the Policy Offer example below, the permission allows the target asset to be printed, and also include a refinement Constraint of less than or equal to 1200 dpi resolution. The refinement is a more narrower semantic of printing, in this case, printing at a specific maximum resolution level.
