RDF QL Issues
    
      - express query comonents in XML
- 
	  - between a lot and too many angle brackets
 
- RDF
- 
	  - express the query as an RDF graph
- leads to reificiation (or misleading assertions)
 
- other (ASCII)
- 
	  - SQL-like
- XPath/XQuery-like
 
- Templating -- express results XML
- 
	  - can re-use XQuery syntax (maybe some implementation?)
