We have external entities updating and receiving the authorization
policies. 
However, we capture this issue already in the security consideration
section in the Common Policy draft. 

The additional issues listed in RFC 3023 regarding 
* validation, 
* system level command execution
* CSS style sheets, XSL transformations, 
* xmldsig usage
* change the display processor environment 

Still, I can, if you want, make a reference to RFC 3023 if you think
that this is, in general, a good idea.

For me this sounds good. 
Still, I sent a mail to the Geopriv ML.
