2.5.38 DXFId

The DXFId structure is a 4-byte unsigned integer that specifies a zero-based index of a BrtDXF (section 2.4.356) record in the collection of all records directly following the BrtBeginDXFs (section 2.4.58) record in the Styles (section 2.1.7.50) part ABNF. A value of 0xFFFFFFFF means no BrtDXF record is used.
