Another way to do this, which may or may not be convenient, is to use an 
XSLT script to tailor a schema for each of your hardware types.  XSLT can 
read multiple documents, so you could have one input document that's a 
skeleton schema, and another with the constraint values, using XSLT to 
merge them.  If you prefer, you could burry the entire skeleton into the 
XSL stylesheet as a template, using a single input document with the key

Ah. Well, W3C XML Schemas don't inhierently support this "dynamic" schema
contruction. You will probably need to use a stylesheet to validate, or
perhaps schematron.
