Internally, every Xic text label object has a set of flags which control presentation and other attributes of the label. The flags are visible in the label specifications in native cell files and default extended CIF files (see B.3). It is also used with script functions (GetLabelFlags, SetLabelFlags, Label, LabelH) and the XprpXform pseudo-property (see 10.1.2).
