I hope that the rest of the TAG is better-educated on this stuff than I 
am, because I just read these two paras and don't understand them in the 
slightest.  I think I basically don't understand the usage of the word 
"type" that's being used here... what do you mean by "typing the query 
parameter"?

An example would really help here.... in many services I'm aware of, the 
receiver & sender of a message both know what the datatypes of the 
message components are supposed to be, so this info isn't included at 
runtime; consider a Google "advanced search" URI

I see no type information.... what am I missing?
