[osis-core] Date problems....

I don't think we got quite as far as to actually name the systems.  
Harry's email to osis-core of 8-29 lists some of the different systems
that were identified.

ISO 8601:2000 says to use 1-7, starting on Monday.

On a related topic, it seems ISO 8601:2000 does identify a manner of
signifying BCE dates, namely negative year values, as we agreed upon.  
However, this won't work for us after all because '-' is a character
reserved for ranges in osisRefs and therefore not allowed in osisIDs.  We
could pick a letter or use '_' to replace the '-'.
