Hi Ellyn,

One problem is that you use file paths instead of URIs to specify the 
included/referred schemas.

Either specify them relatively or use full URIs like
file:/C:/xml/DocBook/xml/rng/docbook.rng
file:/C:/xml/rng/mathml/mathml2.rng

If you sill have problems let me know.

Best Regards,
George
