Uhm good question.

I don't remember anything about the board in the standard. AFAIK the
courtyard is meant as a 'intercomponent' space, so it shouldn't matter.

I do RAST card edges in this way if it helps:


(module "CARDEDGE-RAST25-3" placed (layer "F.Cu") (tedit 514EEA2A)
  (descr "Direct Mating RAST 2.5 edge - 3 pin")
  (attr virtual)
  (fp_text reference "CARDEDGE-RAST25-3" (at 0 0) (layer "F.SilkS")  (effects (font (size 1.2 1.2) (thickness 0.12)))
  )
  (fp_text value "CARDEDGE-RAST25-3" (at 0 0) (layer "F.SilkS") hide  (effects (font (size 1.2 1.2) (thickness 0.12)))
  )
  (fp_line (start 5.75 -8.55) (end 5.75 0) (layer "F.CrtYd") (width 0.01))
  (fp_line (start 5.75 0) (end 5 0) (layer "F.CrtYd") (width 0.01))
  (fp_line (start 5 0) (end 5 -2) (layer "F.CrtYd") (width 0.01))
  (fp_line (start 5 -2) (end -5 -2) (layer "F.CrtYd") (width 0.01))
  (fp_line (start -5 -2) (end -5 -8.55) (layer "F.CrtYd") (width 0.01))
  (fp_line (start -5 -8.55) (end 5.75 -8.55) (layer "F.CrtYd") (width 0.01))
  (fp_line (start 4.4 -4.8) (end 5.6 -4.2) (layer "F.SilkS") (width 0.12))
  (fp_line (start 5.6 -4.2) (end 5.6 -5.4) (layer "F.SilkS") (width 0.12))
  (fp_line (start 5.6 -5.4) (end 4.4 -4.8) (layer "F.SilkS") (width 0.12))
  (fp_line (start -5 -2) (end -5 0) (layer "Edge.Cuts") (width 0.12))
  (fp_line (start 5 -2) (end 5 0) (layer "Edge.Cuts") (width 0.12))
  (fp_line (start 5 -2) (end -5 -2) (layer "Edge.Cuts") (width 0.12))
  (pad "3" connect rect (at -2.5 -4.8) (size 1.7 4.6) (layers "*.Cu" "*.Mask"))
  (pad "2" connect rect (at 0 -4.8) (size 1.7 4.6) (layers "*.Cu" "*.Mask"))
  (pad "1" connect rect (at 2.5 -4.8) (size 1.7 4.6) (layers "*.Cu" "*.Mask"))
  (pad "1" thru_hole oval (at 2.5 -7.5) (size 1.7 2) (drill 0.8 (offset 0 0.2)) (layers "*.Cu" "*.Mask"))
  (pad "2" thru_hole oval (at 0 -7.5) (size 1.7 2) (drill 0.8 (offset 0 0.2)) (layers "*.Cu" "*.Mask"))
  (pad "3" thru_hole oval (at -2.5 -7.5) (size 1.7 2) (drill 0.8 (offset 0 0.2)) (layers "*.Cu" "*.Mask"))
  (pad "" connect rect (at 0 -4.8) (size 8 5.1) (layers "*.Mask"))
)
