At the XML level there is no difference between "extending" an existing
type and creating a new type.  The config doesn't care if, under the
hood, you've extended a class it already knows about.

What you're missing is a basic understanding of XML Schema[1], which, as
the documentation said, is a requirement for creating these new plugins.
 In particular you haven't declared your namespace within the
handler.xml and used the associated prefix with the type.
