+=head2 xml_string(%options, &func)
+
+Convenience function to construct an XML string using the functional interface
+without affecting an existing globally set I<default> object. The I<default>
+object will be set to a newly constructed TUWF::XML object only for the
+duration of C<&func>. The given C<%options> are the same as listed for
+C<new()>, though only the I<pretty> option makes sense for this function.
+Example:
+
+ my $str = xml_string sub {
+ b class => 'hello', 'Hello!';
+ };
+ # $str is '<b class="hello">Hello!</b>'
+
=head2 mkclass(%classes)
Dynamically constructs a I<class> attribute, which can be passed to C<tag()>
