<configfiles>
<inputs name="inputs" format="json" version="1" />

Version is specified as 1, because the Galaxy tool plumbing doesn't really distinguish between parameter is '', parameter was explicitly supplied as None, parameter was absent, etc... - everything is a just a string in some ways. This distinction may be more important with JSON and for instance the CWL will require more percision, so we may want to revise Galaxy's tool handling in a backward compatible way someday.
