;; 1212 release of the ERG; hence mimic GML 0.1 for now, but using an interim
;; delimiter character, while inside GML processing.           (19-feb-13; oe)

;; at this point, only template calls remain (which are harder to parse, owing
;; to variability in the number of parameters); however, once we make ersatzes
;; self-closing GML tags, this will need review.                (19-feb-13; oe)
;; DPF 2020-03-28 - Now that we see nested GML, the following patterns need
;; revising.  Let's try the simplest approach first.
