Gary: Thank you, I'm running Sun Java System Application Server 8.2 and I'll check the classpath for the domain in the morning.

You don't direcly use them.  They are markers that are written into the rendered output from the JSF form component.  The Form and View JSP tags are required by the JSF runtime.  The marker is then replaced with a hidden html input tag that is an encoded serialized representation of the component's state for the page.  The JSF view tag does this parsing. 

 

This trick is needed in JSF 1.1 because the JSP components build the component tree and invoke rendering versus building the entire tree and then invoking rendering.

 

Since you are seeing this maker in the page, it most likey indicates that the Sun RI Form component added it but the Myfaces View Tag was looking for the other marker.  Most app servers are prepackaged with the RI JSF jars that are self registering by the fact that they are in the classpath.  

 

My guess is that the JSF RI jars are in the classpath and you have a mix of JSF runtimes.  I've seen this with WAS 6 and I just had to delete the RI jars for the servers lib folder.
