+/**
+ * SECTION:element-id3tag
+ * @see_also: #GstID3Demux, #GstTagSetter
+ *
+ * This element adds ID3v2 tags to the beginning of a stream, and ID3v1 tags
+ * to the end.
+ * 
+ * It defaults to writing ID3 version 2.3.0 tags (since those are the most
+ * widely supported), but can optionally write version 2.4.0 tags.
+ *
+ * Applications can set the tags to write using the #GstTagSetter interface.
+ * Tags sent by upstream elements will be picked up automatically (and merged
+ * according to the merge mode set via the tag setter interface).
+ *
+ * <refsect2>
+ * <title>Example pipelines</title>
+ * |[
+ * gst-launch -v filesrc location=foo.ogg ! decodebin ! audioconvert ! lame ! id3tag ! filesink location=foo.mp3
+ * ]| A pipeline that transcodes a file from Ogg/Vorbis to mp3 format with
+ * ID3 tags that contain the same metadata as the the Ogg/Vorbis file.
+ * Make sure the Ogg/Vorbis file actually has comments to preserve.
+ * |[
+ * gst-launch -m filesrc location=foo.mp3 ! id3demux ! fakesink silent=TRUE 2&gt; /dev/null | grep taglist
+ * ]| Verify that tags have been written.
