What we have now is:

(pinTYPE SHAPE (at X Y [ANGLE])

(length LENGTH)

(name“NAME” (font[FONT] (size HEIGHT WIDTH) [italic] [bold]) (visible YES))

(number“NUMBER” (font[FONT] (size HEIGHT WIDTH) [italic] [bold])

(visible YES))

(visible YES)

)



So a 3rd consideration is to do what Jean-Pierre suggested, handling
multiple (number....) elements.

Feedback on the 3 ideas is needed at this point. Without feedback I will not
change anything, since multiple pin 'number's can be added later relatively
easily.
