Sameer, I had a Worldcom guy in a class once (will I ever again?) and we 
had a nice back-and-forth on the subject of standards: If a company only 
supports a subset of an RFC or an IEEE standard, is that company complying 
with the standard? His argument was no, mine was yes. There is no right or 
wrong answer here.

For instance, Cisco complies with the LDP standard on only the parts of it 
that they think are important. Although I can't say for sure, I would bet 
that they do not support the whole of the standard set relative to the 
DiffServ model - but they do support some of it, the parts that make sense.

It is likely that most vendors support subsets of many standards, and this 
is where it becomes very important for the buyer, with two vendors claiming 
compliance with a standard, to make sure they comply with the same pieces 
of that standard so the boxes can talk to each other.
