not easy/possible to specify when something is an attribute versus an element using XML::Simple

Actually XML::Simple has a very simple rule for determining whether to output something as an attribute vs a nested element. If the value is a plain scalar, it will be output as an element, otherwise it will be a nested element. E.g.:

print XMLout({person => { id => 123, name => ['John Doe']}})

gives:

<opt>
  <person id="123">
    <name>John Doe</name>
  </person>
</opt>

Having said that, I'd encourage the use of a different module for anything non-trivial.
