    attribute type
XDS: The component of an attribute that indicates the class of information given by that attribute.  It is an Object Identifier, so it is completely unique.   
 XOM: Any of the various categories into which the client dynamically groups values on the basis of their semantics.  It is an integer unique only within the package. 
   Security: The description of the identifiers (such as name and UUID) and semantics (such as encoding type and access control parameters) of 
instances of this type.
