This extended operation identifies a change of prefix. It consists of one
xs:add operation, which show the addition of the new prefix, and one
xd:remove operation, which show the removal of the prefix. There can also be any number of the
xd:change operations with the same opid for each element or attribute name that is affected by the changed prefix.
The following is an example of what a
prefix change element looks like:
<xd:descriptor type="prefix change" opid="3" oldPrefix="xslt" newPrefix="xsl"/>
The preceding example shows that a prefix change has occurred, and shows the old and new prefixes. All operations with an opid attribute with value 3 are part of this action.
The following table describes additional attributes of the
xd:descriptor element for a prefix change operation.
