That's the object generation (or version, if you prefer). A
"garbage collected" PDF will only have generations of 0, since there aren't
any older versions of objects. BUT if you are working with a PDF that has
updates applied to it, then you'll have multiple versions/generations of an
object.
I highly recommend that if you are trying to modify PDF's at this
level, you REALLY NEED to go back and read the PDF specification more!
