Begin Resource (BRS) structured field

ACIF uses this structured field to delimit the resources in the file. ACIF also uses the X'21' triplet on the BRS structured field (also called the BR structured field) to identify the type of resource that follows this structured field. For more information, see Mixed Object Document Content Architecture Reference, AFPC-0004.

For TrueType and OpenType fonts, the 8-character name on the BRS structured field is always DOFFONT. The actual full font name is stored in an FQN triplet on the BRS structured field and is used to match the font to the Map Data Resources (MDR) structured field. For more information, see Using OpenType Fonts in an AFP System, G544-5876.
