The following macro-command assumes that Parent is explicitly selected. 
This is always the case if the command is triggered by a 
command-button() attached to the Parent element.

   <command name="appendChild">
     <macro>
       <choice>
        <command name="insert" parameter="into Child" />
         <sequence>
           <command name="selectNode" parameter="child" />
           <command name="selectNode" parameter="lastSibling" />
           <command name="insert" parameter="after Child" />
         </sequence>
       </choice>
     </macro>
   </command>

Note that the "firstSibling" and "lastSibling" options are not 
documented in the Power User's Guide. This documentation bug will be 
fixed in next release.
