> The existing Read/WriteDOMSessionTransformer was limited to reading/writing to 
> sessions only.  I didn't really like this behaviour, since there are times you 
> only want to store stuff for the duration of a request, and thus not have it get 
> serialized to a persistent store (eg. by Tomcat) if you forget to invalidate the 
> session or delete the DOM object (deletion currently being problematic 
> with Cocoon).
> So I wrote new ReadDOMTransformer and WriteDOMTransformer classes that take an 
> extra parameter specifying whether to read from/write to the session or the 
> request instead.  Default is to write to a session to stay more or less 
> compatible with the older versions.
> Because WriteDOMTransformer parameters were made consistent with the 
> ReadDOMTransformer, it's not a direct drop-in replacement for the older 
> WriteDOMSessionTransformer (it now uses the "attribute-name" parameter instead 
> of the prior "dom-name parameter" which was misnamed,
> IMNSHO).
