## any aspect of an SBML Model that you want to be notified about. You could
## use this to notify your application that a model contains an unsupported
## feature of SBML (either as warning).
##
## In this example the validator will go through the model and test for the
## presence of 'fast' reactions and algebraic rules. If either is used a
## warning will be added to the error log.
