what if you're a proxy? the only way for a proxy to obey the above is to 
transform its input (because if liberal as a server, it should accept 
input that it can't directly forward, because it must be conservative as 
a client), which is not always possible nor acceptable.

I'm not a fan of this robustness principle, even if I understand its 
benefits. the fact that I spent nights and days trying to get some 
proxies work between a silly IE3 and an apache may be a reason...
