=head2 METHODS

=cut

=head3 create

Creates a new zone. Needs all the attributes (name, callerreference and comment).

Takes an optional boolean parameter, C<wait>, to indicate whether the request should
return straightaway (default, or when C<wait> is C<0>) or it should wait until the
request is C<INSYNC> according to the Change's status.

Returns a L<Net::Amazon::Route53::Change> object representing the change requested.

=cut

    my $self = shift;
    my $wait = shift;
    $wait = 0 if !defined $wait;

        Content => $request_xml,

        sleep 2;
        $change->refresh();
    }
    return $change;
}

=head3 delete

Deletes the zone. A zone can only be deleted by Amazon's Route 53 service if it
contains no records other than a SOA or NS.

Takes an optional boolean parameter, C<wait>, to indicate whether the request should
return straightaway (default, or when C<wait> is C<0>) or it should wait until the
request is C<INSYNC> according to the Change's status.

Returns a L<Net::Amazon::Route53::Change> object representing the change requested.
