That is another reason for calling it a *variable*; it is not a
*constant*.  If you read the text at
http://unicode.org/reports/tr35/tr35-general.html#Segmentations, you
would find the statement "The ordering of variables is important; they
are evaluated in order from first to last (see Section 9.1 Segmentation
Inheritance)".
