The way to do this in DSSSL is to use the glyph-subst-table property.  The
Jade RTF backend knows about the AFII glyph ids for small caps and
recognizes when a glyph-subst-table is doing small caps.  One way to create
a suitable glyph-subst-table is like this:

(define *small-caps*
  (letrec ((signature (* #o375 256))
	   (make-afii
	    (lambda (n)
	      (glyph-id (string-append "ISO/IEC 10036/RA//Glyphs::"
				       (number->string n)))))
	   (gen
	    (lambda (from count)
	      (if (= count 0)
		  '()
		  (cons (cons (make-afii from)
			      (make-afii (+ from signature)))
			(gen (+ 1 from)
			     (- count 1)))))))
    (glyph-subst-table (gen #o141 26))))

The just use

  glyph-subst-table: *small-caps*
