This directory contains tools to handle IPP attributes based on data provided in IPP registrations. The authoritative source for CSVs in this directory is the registrations page hosted by IANA (direct link to Attributes CSV, direct link to Keyword Values CSV, direct link to Enum Values CSV).
If CSVs are updated one should be able to drop in the new version as is but localizations might have to be added to components/printing_component_strings.grdp. TODO: Generate placeholders in grdp.
