OK, HTLC.ME (cool site!) uses a description of:

        {"generic_id":"ada00363-50b6-4281-82dd-d274393439f1"}

Which I really don't understand.  This field is literally only to
display to the user, for them to validate it's what they wanted.  The
recipient never gets it back.

If I knew who ran HTLC.ME, I'd ask them to fix it: they should have a
description entry field in their "Request Payment" form.  It could
default to "Test payment ada00363-50b6-4281-82dd-d274393439f1", but
they're in spec violation at the moment.

Easy to do, if I knew why they wanted it.

Thanks!
Rusty.
