Subject: Re: [office] [OASIS Issue Tracker] Commented: (OFFICE-3297) Part 3[Blowfish] Reference Out-of-Date, Misleading


The TC needs to make a choice about how to treat references that may be
updated but I don't know that it is "problematic." 

It is entirely permissible for the TC to chose to base conformance on a
particular version of another standard. For example, a standard could
cite Unicode 4.0 and say that conformance was based on support for
Unicode 4.0 and no later versions or amendments to the same. 

I choose Unicode because the usual case is that standards reference the
current version and any later editions. 

I don't think that causes much of an issue because conformance to
Unicode can extend to a subset of characters and abilities.

I don't recall seeing a standard that chose to include later editions of
some standards but specific versions of others. Will have to investigate
that as a possibility.

Hope you are having a great day!

I don't know if there ever will be a 3rd edition of Applied  Cryptography, but if so, it may happen that the URI refers to that. Further, the document the URI refers to may get amended. Both may be considered problematic for a normative reference.
