However, as would be obvious to people with more OO experience than I have, when the output sub in a Resume::Text object calls apply_stylesheet (which is defined in the parent Resume package, rather in the child Resume::Text package), the the sub tries to read the data in the __DATA__ section of Resume.pm, not the one in Resume/Text.pm.

You can deal with this problem by further isolating your use of the __DATA__ section behind a method that does a one-time, lazy setup from <DATA>. This turns   my $doc = $self->{'parser'}->parse_string(<DATA>); into 

  my $stylesheet = $self->get_stylesheet();
  my $doc = $self->{'parser'}->parse_string($stylesheet);

This also frees you to override get_stylesheet() in subclasses. How and where get_stylesheet() gets the stylesheet is an implementation detail. A subclass needn't use the __DATA__ section.
