I can see how DCWorkflow can change the permission (state) of a 
portal_type object, but I could not figure out how to use DCWorkflow to 
change the state of a specific action of a portal_type object.

My objective is, basically, to dynamically change the Plone content tabs 
(which use the portal_type object actions to draw some of the tabs) with 
my MailMessage object.

Thanks,
