public class SourcePropsWritingTransformer
extends AbstractSAXTransformer

This transformer allows you to set and remove properties on an InspectableSource.

Input XML document example:

 <page>
   ...
   <source:patch xmlns:source="http://apache.org/cocoon/propwrite/1.0">
     <source:source>webdav://localhost/webdav/step1/repo/contentA.xml</source:source>
     <source:set>
       <myns:author xmlns:myns="meta">me</myns:author>
     </source:set>
     <source:remove>
       <myns:title xmlns:myns="meta"/>
