One thing that we noticed when implementing stylesheet chaining/pipelining/
whatever in 4Suite (see, I can advertise, too) is the problem of what to do
with external stylesheet parameters. Say you want to pass the output of
stylesheet 1 to stylesheet 2, and stylesheet 2 needs some top-level parameters
passed in. For now we just don't do anything; only the first stylesheet in the
chain gets that privilege. So I'm curious... what does your system do in this
regard? Or if you prefer not to divulge, what do people think a system
*should* do?
