+ * An interface extending List&lt;String&gt; that also provides access to the
+ * items of the list as UTF8-encoded ByteString objects. This is used by the
+ * protocol buffer implementation to support lazily converting bytes parsed
+ * over the wire to String objects until needed and also increases the
+ * efficiency of serialization if the String was never requested as the
+ * ByteString is already cached.
+ * <p>
+ * This only adds additional methods that are required for the use in the
+ * protocol buffer code in order to be able successfuly round trip byte arrays
+ * through parsing and serialization without conversion to strings. It's not
+ * attempting to support the functionality of say List&ltByteString&gt, hence
+ * why only these two very specific methods are added.
