Hi,

DNC is based on VPF format.

http://msi.nga.mil/NGAPortal/DNC.portal;jsessionid=v7pkSThJG9vQcrQ0yTwLxTL1hQmyhGbFJQLZCJTW5dGJJjT0GmJX!1413119135!NONE?_nfpb=true&_st=&_pageLabel=dnc_portal_page_70&faqCode=02

The styling is defined by a different standard as a set of geosym rules.

Regards
Damian
