The regular expression uses the notation defined in POSIX Standard 1003.2 for extended
(modern) UNIX regular expressions. Explaining regular expression syntax is beyond the
scope of this document, but Table 7 on page 91 specifies which character or characters
are matched by some of the regular expression operators that can be used in the
expression. In the descriptions, the term term refers to either a single alphanumeric
character or a set of characters enclosed in square brackets, parentheses, or braces.
NOTE: The attribute is not case-sensitive.
