That part has seen many revisons by Lego themselves.

Do you know which version your's is from?

At first glance I'd say it's simply a "molding relict" which is typically not rendered in LDraw.

It looks like an "Ejection Mark", meaning it's a stamp left on the part when it is thrown out of the mold (by metal ejection pins) after being cooled down. Those typically have no function (in the final part) and as such are not rendered in LDraw.

EDIT:
Ok, that can't be an Ejection Mark. It still seems to have no direct function... How does it look on a minifig?
Also those holes are more interesting than the protrusion I'd say...
