 Does it make sense to have 2 handlers for the same URI schema? Do you just
mean to use this as a way to temporarily override some handler (i.e. add a
custom handler at the beginning of the list disabling the existing one and
then remove the custom handler reenabling the old one) or do you see any
other uses for this?

 BTW, another possibility would be to just make AddHandler() add the new
handler in the beginning of the list because I think most (all?) of the
time you want the last added handler to be the most prioritary one.

 The Add/Append confusion is unfortunately quite wide spread in wx API :-(

 Yes, we should definitely document how all this works, whatever we choose.
