=head1 NAME

XML::SemanticDiff::BasicHandler - Default handler class for XML::SemanticDiff

=head1 SYNOPSIS

  use XML::SemanticDiff;
  my $diff = XML::SemanticDiff->new();

  foreach my $change ($diff->compare($file, $file2)) {
      print "$change->{message} in context $change->{context}\n";
  }

=head1 DESCRIPTION

This is the default event handler for XML::SemanticDiff. It implements nothing useful apart from the parent class and should
never be used directly.

Please run perldoc XML::SemanticDiff for more information.
