a specific group of attributes.
In cell XFs:
- ``flag==0`` means the attributes of the parent style ``XF`` are
used, (but only if the attributes are valid there);
- ``flag==1`` means the attributes of this ``XF`` are used.
In style XFs:
- ``flag==0`` means the attribute setting is valid;
- ``flag==1`` means the attribute should be ignored.
.. note::
the API provides both "raw" XFs and "computed" XFs. In the latter case,
cell XFs have had the above inheritance mechanism applied.
