Subclass marker (AcDbRegAppTableRecord)

2

User-supplied (or application-supplied) application name (for extended data). These table entries maintain a set of names for all registered applications

70

Standard flag values (bit-coded values):

16 = If set, table entry is externally dependent on an xref

32 = If both this bit and bit 16 are set, the externally dependent xref has been successfully resolved

64 = If set, the table entry was referenced by at least one entity in the drawing the last time the drawing was edited. (This flag is for the benefit of AutoCAD commands. It can be ignored by most programs that read DXF files and need not be set by programs that write DXF files)
