           Returns a version string for the module.

TESTS

       syntax01($name)
           Verifies that the name (Zonemaster::Engine::DNSName) given contains only allowed
           characters.

       syntax02($name)
           Verifies that the name (Zonemaster::Engine::DNSName) given does not start or end with
           a hyphen ('-').

       syntax03($name)
           Verifies that the name (Zonemaster::Engine::DNSName) given does not contain a hyphen
           in 3rd and 4th position (in the exception of 'xn--').

       syntax04($name)
           Verify that a nameserver (Zonemaster::Engine::DNSName) given is conform to previous
           syntax rules. It also verify name total length as well as labels.

       syntax05($zone)
           Verify that a SOA rname (Zonemaster::Engine::DNSName) given has a conform usage of at
           sign (@).

       syntax06($zone)
           Verify that a SOA rname (Zonemaster::Engine::DNSName) given is RFC822 compliant.

       syntax07($zone)
           Verify that SOA mname of zone given is conform to previous syntax rules (syntax01,
           syntax02, syntax03). It also verify name total length as well as labels.

       syntax08(@mx_names)
           Verify that MX name (Zonemaster::Engine::DNSName) given is conform to previous syntax
           rules (syntax01, syntax02, syntax03). It also verify name total length as well as
           labels.

INTERNAL METHODS

       get_name($item)
           Converts argument to a Zonemaster::Engine::DNSName object.

       check_name_syntax
           Implementation of some tests that are used on several kinds of input.
