The only interesting thing aobut a DIFF method is the format of its 
result.
There was such a wide variation in the different formats that diff tools
use for different types of resources that it didn't appear to be something
on which we could get consensus.  There are some standards for diff 
formats,
e.g., http://www.ietf.org/rfc/rfc3284.txt?number=3284 (The VCDIFF Generic
Differencing and Compression Data Format) and some new ones being
proposed, e.g., 
http://www.ietf.org/internet-drafts/draft-ietf-simple-xcap-diff-03.txt

Cheers,
Geoff
