[ur-wg] XML Schema validation

[Thomas Sandholm]

Hi,

I ran the schema at:
http://www.psc.edu/~lfm/Grid/UR-WG/urwg-schema.11.xsd
through the official W3C validator at:
http://www.w3.org/2001/03/webdata/xsv

and got the following errors:
http://www.psc.edu/~lfm/Grid/UR-WG/urwg-schema.11.xsd:327:3: Invalid: 
attempt to derive a complex basetype from a simple base: ConsumableResourceType
http://www.psc.edu/~lfm/Grid/UR-WG/urwg-schema.11.xsd:336:3: Invalid: 
attempt to derive a complex basetype from a simple base: ConsumableResourceType

What tools have you used to validate this schema? And do you have any 
comments on the errors above?

Thanks,
    Thomas
