Allow handled properties not to have a short name

Shorten a json representaion allows the properties that the parser
doesn't knonw to be left unshortened. This is applicable to other
properties that the parser knows *but* don't shorten
intentionally. This is convenient some properties to be handled but
rarely seen.
