Rocky Burt Subtyping Unleashed

The document discusses subtyping in Plone and presents an example of creating a new document subtype called "UltraDoc" using the p4a.subtyper package. The example shows how to define a marker interface, descriptor class, template, and ZCML configuration to integrate the new subtype into Plone so it appears as its own content type with a customized view. The presentation aims to demonstrate how subtyping can be used to provide different identities for content and transform content based on events.
