+=head1 SYNOPSIS
+
+  use MooseX::Validation::Doctypes;
+
+  doctype 'Person' => {
+      id    => 'Str',
+      name  => 'Str',
+      title => 'Str',
+  };
+
+  use JSON;
+
+  my $data = decode_json('{"id": "1234-A", "name": "Bob", "title": "CIO"}');
+
+  use Moose::Util::TypeConstraints;
+
+  my $person = find_type_constraint('Person');
+  my $errors = $person->validate($data);
+
+  use Data::Dumper;
+
+  warn Dumper($errors->errors)     if $errors->has_errors;
+  warn Dumper($errors->extra_data) if $errors->has_extra_data;
+
+=head1 DESCRIPTION
+
+This class holds the errors that were found when validating a doctype. There
+are two types of errors: either an existing piece of data didn't validate
+against the given type constraint, or extra data was provided that wasn't
+listed in the doctype. These two types correspond to the C<errors> and
+C<extra_data> attributes described below.
+
+=cut
+
+=attr errors
+
+Returns the errors that were detected. The return value will be a data
+structure with the same form as the doctype, except only leaves corresponding
+to values that failed to match their corresponding type constraint. The values
+will be an appropriate error message.
+
+=method has_errors
+
+Returns true if any errors were found when validating the data against the type
+constraints.

 has errors => (
     is        => 'ro',
     predicate => 'has_errors',
 );
 
+=attr extra_data
+
+Returns the extra data that was detected. The return value will be a data
+structure with the same form as the incoming data, except only containing
+leaves for data which was not represented in the doctype. The values will be
+the values from the actual data being validated.
+
+=method has_extra_data
+
+Returns true if any extra data was found when comparing the data to the
+doctype.
