Clarification of ISO-IEC 18014 documents

[Young H Etheridge <yhe@xxxxxxxxxxxxxxx>]

Carl,

A clarification of the ISO 18014 documents may be useful. 

ISO-IEC 18014-1-2002 uses the term TS reissue to intend TS renewal in 
the terms as expressed in WG communications of late.  I quote:  
"A time­stamp re­issue may also be necessary when 
the hash-­function used to form the hash value from 
the original data is called into question.  In this case, 
both the old time­stamp token and the original data 
must be included in the newly calculated hash value
submitted for time­stamp reissue."

A revision of 18014-1 is in-progress.  The term reissue is being 
replaced with renewal along with descriptive information that makes the 
point clear that a renewal contains a hash of the data along with the 
hash of the original TS that is being renewed.  The new description is 
quite clear in regard to creation and verification of renewal.

Furthermore, ANSI X9.95 is consistent on renewal with those found in 
18014-2-2002, 18014-3-2004 and the revision of 18014-1-2002.

I hope this helps.
