Imagine I have a base declaration of a component, say <cmp:OnFault cdl:extends="cmp:Notification" faultName="" faultType="" /> now, imagine I extend that in a new namespace Should I put the attributes in the namespace of the component I extend <tns:MyFault cdl:extends="cmp:OnFault" cmp:faultName="DeploymentFault" /> Or can they be left as is: <tns:MyFault cdl:extends="cmp:OnFault" faultName="DeploymentFault" /> That is, when we merge attributes, do we use the full QName, or just the localname. I know it would appear to make sense to use the full qname, but the trend to use unqualified attributes may cause confusion here. I know my parser already warns whenever it hits an unqualified extends="" attr, as that is often a result of me forgetting that namespace.... -steve
