Spaces in IDs: was Re: [osis-core] Harry on osisID's

[Harry Plantinga]

What I was looking for was not just a way of validating 
the syntax of osisRefs for augustine's confessions, but 
saying what they correspond to in the document.

See my earlier post suggesting a reference version of 
augustine's confessions.
