Description

We're extracting PDFA part and conformance. We should add extraction for VT, UA, and X.

We should also finally get rid of the bad hack from 1.x that appended the pdfa conformance to the file type.

I'd like to thank Peter Wyatt via offline chat for everything that was right about this improvement. The other stuff is all mine.
