+
+=head1 DESCRIPTION
+
+B<Travel::Routing::DE::EFA::Route::Message> contains information about a
+specific route or route part, such as wheelchair accessibility, unscheduled
+route diversions and cancelled stops. Often, this information is not used in
+the backend's route calculation, so a message may invalidate a certain route or
+route part.
+
+There are two types of messages provided by the backend: oneliners and detailed
+messages. There is no known distinction regarding their type or content.
+Also, there are some other backend-provided fields not yet covered by this
+module, so expect changes in future releases.
+
+A oneline message consists of a single string which can be accesed using
+B<subject> or B<summary> and its B<is_detailed> accessor returns false.
+
+A detailed message has a subject, subtitle, summary and detailed HTML
+content.
+
+=head1 METHODS
+
+=head2 ACCESSORS
+
+=over
+
+=item $message->is_detailed
+
+True if all accessors (fields) are set, false otherwise. When this field
+is false, only B<summary> and B<subject> are set (and they will return the
+same string).
+
+=item $message->summary
+
+Message summary.
+
+=item $message->subject
+
+Message subject. May be the same string as the subtitle.
+
+=item $message->subtitle
+
+Message subtitle. May be the same string as the summary.
+
+=item $message->raw_content
+
+Raw HTML content. May contain information not available via any other
+accessor.

+=head1 DIAGNOSTICS
+
+None.
+
+=head1 DEPENDENCIES
+
+None.
+
+=head1 BUGS AND LIMITATIONS
+
+This module does not yet provide access to all data provided by the backend.
+Most notably, B<raw_content> is not properly parsed yet.
