I would like to see a single string that identifies reference 
system, work, and osisID.

Todd's proposal is fine with me, or any syntax that puts it all
into a single string. The workID should be optional.

One issue that seems to me to be unresolved is this: does the 
workID merely point to a <work workID="xxx"> element, or does
it have some external significance?  If external, how are these
things defined, kept unique, etc?  Same thing for reference
system identifiers.
