Don't know... The docs do say there may be trouble using the default
rules of SGML::EntMan when calling SGML::DTD. So I'd guess that you need
to construct your own EntMan object and pass that to the DTD object.

Well the ARRAY(0x8286e40) thing means that it's an array reference.
Dereference is and bob's your uncle. So when you foreach over
$attributes{$_} check to see if $_ is an array ref, the 'ref' call is
your friend. If it is then deference it and iterate over it.

At this point it is traditional to mention 'use strict' and warnings.
You use them in the first, but not the second script; what's that all
about then Ted?

Also better to check when you open the file if it has succeeded.

There ends the sermon :)
