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