A higher level tutorial on XML and Perl would be good- something that gives a brief over-view of what it is and what it is good/bad for (in a Perl context) and surveys the available modules and their strengths & weaknesses, possibly over-lapping with ajt's suggested structured markup tutorial.

Not sure if any-one uses it much any-more but I have previously wanted for a Perl Curses tutorial.
