This needs to be rethought, and I'm hoping to get a chance to rethink

It's a variant of Gambit-C and SRFI 91, using p-lists instead of keyword
arguments. It has the advantage that you can add more features to the
various file openers without adding more and more procedures to handle
them, or having to open them and then use various setters which can
potentially be called at any time.

Editorial ticket filed.

Changed to file-spec.
My confusion is rapidly waxing John Cowan
For XML Schema's too taxing: cowan@x
