This lets you provide information like relative page numbers by evaluating a string as an expression.

Check out our docs page on this.

Example usage

<story>
    <namedString id="LASTPAGENO"><pageNumber/></namedString>
    <para>
        The last page is <getName id="LASTPAGENO" default="-999"/>
        One less than that is
        <evalString default="XXXX"><getName id="LASTPAGENO" default="-999"/> - 1</evalString>
    </para>
</story>
