 PrincipalPermissionAttribute can be applied only on Class and Method 
 and supports Demand (checked at runtime), LinkDemand (checked at JIT 
 compilation) and InheritanceDemand (checked at load time).

+The security attributes are kept in the assembly metadata as XML 
+strings. The XML strings always seems to represent a PermissionSet.
+corlib has an internal parser, SecurityParser based on MiniParser, 
+that can return a SecurityElement.
+A static method could be added to SecurityParser to return a 
+PermissionSet directly from the XML string.
+static PermissionSet FromXmlString (string xml) 
+	SecurityParser sp = new SecurityParser ();
+	sp.LoadXml (xml);
+	PermissionSet ps = new PermissionSet (PermissionState.None);
+	ps.FromXml (sp.ToXml ());
+	return ps;
+This should simplify the number of operation required by the runtime 
+to start a SecurityAction, e.g. (in pseudo-code)
+PermissionSet ps = SecurityParser.FromXmlString (metadataXML);
+ps.Demand ();
