If I understand you correctly, you're suggesting that ports be
"typed". So some ports are "text" ports and some are "xml" ports. You
can only connect together ports of the same type.

How does that actually solve the problem at hand? By having multiple
ports?

  <p:declare-step type="p:validate-relax-ng">
    <p:input port="schema-xml" type="xml" .../>
    <p:input port="schema-rnc" type="text" .../>
    ...
  </p:declare-step>

Then you need co-constraints. Or maybe you're thinking that ports
should be polymorphic? So the "schema" port of the component accepts
either "xml" or "text" depending on what sort of output its connected
to.

That still leaves the question of who decides what's actually flowing
through the pipe and how and when.

I'm not sure I like the idea, but I am (pretty) sure I don't want to
tackle that in V1.
