Yes, thinking that EMPTY is a special keyword.

It would appear that it wasn't Martin that prodded me into EMPTY 
support as Cadcorp SIS doesn't support any of these variations yet.
I am adjusting the OGR implementation to product in the form
"POINT EMPTY" though I will continue to consume "POINT(EMPTY)"
as well.  

Were some people thinking that EMPTY was a special keyword meaning
nothing at all in EBNF?
