Re: Final SPKM draft...

Hi there,


the ASN.1 type defintion of REP_TI_TOKEN in the new SPKM draft 
(draft-ietf-cat-spkmgss-05.txt) contains one ambiguity regarding
the 2 DNs (src_name and targ_name), one of which is OPTIONAL
(src_name). The current definiton puts the OPTIONAL name first,
which causes an ambiguity, since an ASN.1 parser cannot determine
if the first Name it encounters is src_name or targ_name:



   REP_TI_TOKEN ::= SEQUENCE {

		...

           src_name         Name OPTIONAL,
           targ_name        Name,

		...
           }



The correct definition should put the OPTIONAL name last:


   REP_TI_TOKEN ::= SEQUENCE {

		...

           targ_name        Name,
           src_name         Name OPTIONAL,

		...
           }


This corresponds to the order found in REQ_TOKEN and REP_IT_TOKEN.
