RelaxNG syntax conversion in XProc 3

Hello XProc friends,

Does anyone have any tips for a pipeline (step) to convert between RelaxNG
and RNC (RelaxNG compact) syntax?

The feature is built into Trang (IINM) and I dare say almost any RNG
implementation (?) but I am not sure I would know how to configure either
XML Calabash, or Morgana, to invoke it.

As always I'm grateful for any tips --

Regards, Wendell
