sl@0: * Description: 
sl@0: * This file contains the implementation of the ASN1 Set and Set-of object, 
sl@0: * as described in X208 Sections 22 and 23 and X209 Sections 16 and 17. The 
sl@0: * set object can contain an ordered series of zero, one or more other ASN1 
sl@0: * objects. The set-of object contains zero, one or more of the objects 
sl@0: * described in its definition. The data encodings of both these objects is 
sl@0: * identical. The ordering of the elements contained within set objects is not
sl@0: * significant.
sl@0: * The implementation of sets is pretty much the same as that for sequences 
sl@0: * (indeed it has started from a straight cut'n'paste) but there are some 
sl@0: * significant differences with regard to ordering of items within the set,
sl@0: * comparison and retrieval of items.
