This example is perfectly OK. In XML almost all whitespace in element 
content shouldn't be discarded. Thus you should omit new line right 
after start tag and right before end tag:

<informalexample>
<programlisting>sub print_content_model {
     my($self) = shift;
     local($_) = shift;
     local(*FILE) = shift;

     my(@cm) = $self->format_content_model2($_);
     foreach $_ (@cm) {
         print FILE $self->make_links($_, 1, 1), "\n";
     }
}</programlisting>
</informalexample>

Tidy is tool for cleaning up HTML code, not XML processor.
