Besides the backslash thing, there are a number of URI processing  
rules that browsers must follow for web compatibility which are  
either not required by or directly contradictory to the URI RFCs.  
Documenting these and fixing the relevant RFCs would be a valuable  
goal, but possibly beyond the scope of WHATWG.
