Subject: Schema - Require attribute in specific node

In the sample XML below, I would like to require the franchise attribute on the forms node only when the business_line type attribute equals "hardware". The match to hardware could happen on the business or forms node's type attribute. I don't have the option to change the xml.

<company>
<business_line type="hardware">
<forms type="hardware" franchise="Y">
<form>form1</form>
</forms>
</business_line>
<business_line type="laundromat">
<forms type="laundromat">
<form>form1</form>
</forms>
</business_line>
</company>

Such constraints cannot be enforced using XML Schema, consider using XSLT or XQuery

Hope this helps
