Steps refer to types but you refer to steps via their name.  Hence, when
tracing a flow, you are referring to a step via its name and qualify
that with a port name.

At the end, you have a unique set of component type names as determined

    * the "built-in" component types
    * any declare-component definitions in the pipeline
    * any libraries that you import.

This is a "flat" set of component types and so you can't have
