     * 
     * In the commented code below, the check for editAllowed will never be 
     * seen on a parameter element in the 
     * current database schema approach used by DLM. This is because 
     * parameters are second class citizens of the layout structure. They
     * are not found in the up_layout_struct table but only in the 
     * up_layout_param table. DLM functionality like dlm:editAllowed,
     * dlm:moveAllowed, dlm:deleteAllowed, and dlm:addChildAllowed were 
     * implemented without schema changes by adding these as parameters to
     * structural elements and upon loading any parameter that begins with
     * 'dlm:' is placed as an attribute on the containing structural 
     * element. So any channel parameter entry with dlm:editAllowed has that
     * value placed as an attribute on the containing channel not on the 
     * parameter that was meant to have it.
     * 
     * The only solution would be to add special dlm:parm children below
     * channels that would get the editAllowed value and then when creating
     * the DOM don't create those as child elements but use them to set the
     * attribute on the corresponding parameter by having the name of the
     * dlm:parm element be the name of the parameter to which it is to be 
     * related.
     * 
     * The result of this lack of functionality is that fragments can't 
     * mark any channel parameters as dlm:editAllowed='false' thereby
     * further restricting which channel parameters can be edited beyond 
     * what the channel definition specifies during publishing.
