+ * The different tag merging modes are basically replace, overwrite and append,

+ * e.g. via gst_tag_setter_merge_tags() / gst_tag_setter_add_tags() or a
+ * %GST_EVENT_TAG), how are these tags merged?
+ * In the table below this is shown for the cases that a tag exists in the list
+ * (A) or does not exists (!A) and combinations thereof.
