Ok thanks, Jose.

Reading the RR p. 172, I see this text:

A "format" is a structured value (i.e., an internal object) of mode
'FORMAT', which mirrors the hierarchical structure of a format-text (which
is an external object).

I'm reading that as the compiler will itself convert format-text pseudo
denotations into structured values of mode Format; that is, the parsing of
the format-text and the translation into a format structure happens at
compile time.  Is that correct?

If so, then I suppose we need the definition of mode Format and any related
modes before the compiler can implement the parsing and translation... does
that make sense?
