        This characters block encodes restriction site data, i.e.
        presence (1) / absence (0) observations. Because the states
        that can occur - and what they mean - are known, there is no
        'format' element to define states (see below for examples of
        that). In this example, restriction site data is encoded
        as a sequence of characters (rather than individual cells),
        hence we use the subclass xsi:type="RestrictionSeqs".
        
        All characters blocks must have an id attribute and a 
        reference to a taxa block that precedes it. In addition,
        it may have the same additional attributes (label, xml:base, 
        xml:lang, xml:id, xlink:href and class) as the taxa element.
