> Is there a way I can condition a variable on the presence (or absence) >of another variable? no, variables denote values so you can't reference an undeclared variable. There is never any need. Just declare the variable chapter with definition / (your suggested default was the empty sequence but I suspect that you meant / as otherwise paths starting at $root-node would all be empty) so that it can be used stand-alone, and when you import this styleshete into another styleshete the importing stylesheet can supply a non empty definition that will have higher import precedence.
