Valid Content

The content for a pattern follows the digit map rules of RFC 2705, supplemented by the rules for regular
expressions. Where there is an overlap between the digit map and regular expression rules, the digit map rules
apply. For this reason, there are some special cases, included in the table below.

The following table describes the most common elements. As mentioned, all regular expression elements are
supported.

more times, which means this pattern matches three or more digits (not four or more
digits)! Use of this element results in a pattern with “minimum requirements”.
