question: static boolean analyzePredicate ( Compiler compiler , int opPos , int stepType ) throws javax . xml . transform . TransformerException { int argLen ; switch ( stepType ) { case OpCodes .

target:  Analyze a step and give information about it's predicates.  Right now this just returns true or false if the step has a predicate.
