okular cerfa_14952-01_procuration\ de\ vote.pdf

If I select "show forms", I get the warning:
"This document has XFA forms, which are currently unsupported."

What are those?
What difference does it make?
Should I care?
Does another software support XFA forms? Will okular support them in the future?
