To quote from the page: id: flags type: u1

This seems to say flags is a sort of unsigned integer.

Is there a way to break the flags into big endiaN bits where the first two bits are either 01 or 10 but not 00 or 11 with 01 meaning DATA and 01 meaning POINTER with the next five bits as a counter of segments and the next bit is 1 if the default is BLACK and 1 if the default is WHITE ?
