Any logic based on the value of an attribue seems like "business specific" logic more than a schema rule.
Personally, I would like my application to make that decision rather than in an XSD. So, if I were to write the rule I will expect everyone to have a quality attribute and leave it to the application to make sense of it.
All providers must provide a quality and then have a seperate list of trusted-providers. If a provider is in the trusted-provider list, ignore the quality. This is how I would do it in the application.
My two cents.
Thanks.
