The two that I can think of right now are --

CON_USB_MINI_B__Molex_67503-1020 at
http://www.luciani.org/geda/pcb/footprints-gif/Connector-gif.html
IIRC the hashed area is a keepout (at least it has been all of
my designs ;)

For ANT_FOLDED_DIPOLE__Chipcon_2500

The keepout is indicated by a single line.

Just layout hints nothing fancy.
