MooseX::MetaDescription - A framework for adding additional metadata to Moose classes

  package Foo;
  use metaclass 'MooseX::MetaDescription::Meta::Class' => (
      # add class-level metadata
      description => {
          'Hello' => 'World'
      }
  );
  use Moose;

  has 'bar' => (
      metaclass   => 'MooseX::MetaDescription::Meta::Attribute',
      is          => 'ro',
      isa         => 'Str',   
      default     => sub { Bar->new() },
      # add attribute level metadata
      description => {
          node_type   => 'element',
      }
  );

  my $foo = Foo->new;

  $foo->meta->description; # { 'Hello' => 'World' }

  my $bar = $foo->meta->get_attribute('bar');

  # access the desciption HASH directly
  $bar->description; # { node_type   => 'element' }    

  # or access the instance of MooseX::MetaDescription::Description
  $bar->metadescription;

  # access the original attribute metaobject from the metadesc too
  $bar->metadescription->descriptor == $bar;

MooseX::MetaDescription allows you to add arbitrary out of band metadata to your Moose classes and attributes. This will allow you to track out of band data along with attributes, which is very useful for say serializing Moose classes in HTML or XML.
