I've been thinking a bit more about this issue. On the assumption that 
we allow specifying pipeline parameters (like step/component parameters 
- which I would like to have in the language), shouldn't we allow 
conditionals over these parameters? I wouldn't like to have to produce a 
document for activating a simple debug flag inside an XProc-based 
application, for instance.
