what's "extra" ? compared to what ??

You need to add centering devices. Flatness requirements, finish requirements. Corner taps, tap pockets. Machinining after welding to square/true the flanges relative to pipe centerline.
Probably missed a few.
Maybe buy a copy of the standard and read up on it?

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.

From a gas measurement perspective, an "orifice flange" really should be called an "orifice-holding flange" (basically a standard flange with pressure sensing ports on both flanges). The actual flanges are just raised-face flanges with ports drilled and tapped. I've been assuming that this discussion was about the paddle plates that go between the flanges. Just about every answer above has taken that path. If he is really asking about the flanges then they get drilled and tapped.
