Yes, but it hasn't come up often after Ant 1.4 ;-)

One of the reasons (and my main one) is that you'd soon need an
expression language since simple listing two properties isn't enough?
Does if="a,b" mean "either a is set or b" or "a is set and b"?

And then the example above doesn't work since "," is a legal character
inside of property names, as is " " or any other character.  There
could be a property named "a,b".
