Here are some sample cell headers to illustrate this section:
115 17
The above cell header defines a vector list (cell type 115). 17 is the decimal representation of the binary value 10001. Looking at the bits making up the value 17, we see that we need to set bits 0 (value 1) and bit 4 (value 16) and clear all the other bits; consequently, we can deduce that the vector list's attributes are present and that it inherits its color from its parent set.
700 5
This cell header defines a set (cell type 700) for which a set of attributes and geometry have been defined (5 decimal = 101 binary, therefore bits 0 and 2 are set).
