There is use of the word "enforcing" as applied to security labeling. I think this is the wrong word. The security labeling is not enforcing. It is informing. In the XACML model it is "Policy Information", it is not policy enforcing.  The concept seems to be well intended, I just think that using the word "enforcing" is reaching beyond what is actually provided by a security labeling mechanism.

Yet, at this late hour I don't know a better word.
