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 does not need to be set by programs that
write DXF files)
