"How-to" request

[Marco Antoniotti]

Thanks Robert.

AFAIAC the operation-done-p did the trick.  I had skipped it as the doc
says that this operation "may" be provided.

I am not sure how to improve the docs for this task (creating new
operations).  I guess a description of what OPERATE and PERFORM actually
invoke and when would help.

All the best

Marco
