And here is my error when I try to process it: [ERROR] A property with the same name "Value" is generated from more than one schema component.

The schema is in fact a partial schema for the struts-config.xml file. I only have one definition of the attribute 'value', so this error bewilders me. Can anyone explain (a) what is going on and (b) how to resolve this problem?
