Namespace Change Operation

This extended operation identifies a change of namespace declaration. It consists of one xd:add operation, to show the addition of the new namespace declaration, and one xd:remove operation, to show the removal of the old namespace declaration. Additionally, the XDL Diffgram may contain any number of the xd:change operations with the same opid for every element or attribute name that has its namespace URI changed due to this action.

The following is an example of what a namespace change element looks like:

<xd:descriptor type="namespace change" opid="3" oldNs="http://some.uri" newNs="http://updated.uri"/>

This shows that a namespace change has occurred, and shows the old namespace and new namespace. All operations with an opid attribute with the value 3 are part of this action.

The following table describes additional attributes of the xd:descriptor element for a namespace change operation.
