 From your example, it sounds like every pre-coordinated "heading" gets 
its own authority description, as do its individual components. If this 
were done programmatically with LCSH, wouldn't the result be loads of 
syntactically "valid" but nonsensical combinations?

Re: MADS RDF, is there anything to read/look at right now, or should I 
sit on my hands for a week or two?
