V.next idea: option/parameter typing and error handling

Also, as I'm binding certain typed values to options (e.g. pulling a
start time off the query parameters), I'd really like an easy way to

  "This option is typed as xs:dateTime.  If the value does not cast
properly, run this other part of the pipeline."

One simple way we could accomplish this is to allow type errors within
a certain portion of the pipeline to be caught and processed somehow.
