Good question as SecurityAttribute derives from Attribute. The best* way to
know this is to try it on the MS runtime (if you don't have MS runtime
accessible then I can help you on IRC).
* Actually the real best way is to write this as a unit test so it can be
reused afterward to ensure that the feature won't get broken in future
versions of Mono.

I'm not sure where you are exactly when doing this.
When generating assemblies adding permissions is done by calling
AddDeclarativeSecurity. The security attributes are executed by the
compilers (like mcs) to generate the XML (which is then stored in the
compiled assembly metadata).
The security attributes are encoded as permission sets in the metadata as
XML. PermissionSet.FromXml will be able to recreate the permissions (once
you have the XML).
