because when you are resolving the URI server side, what;date=1234 is a 
different element than what;date=5678. (like different archives, for

Yes (but in that case the last / should be escaped). Unlike above, the 
leaf is 'what' with the parameter date=5678%2Ftest or date=1234%2Ftest, 
instead of 'test' (and two different 'test' as the container is different, 
in the first example).

In that case, the resource is the same http://example.com/what, you are 
just addressing different fragments of the same resource, and not two 
different resources, like in the first two examples.
