+Subject: [PATCH] doc/reference: don't add empty object hierarchy chapter
+
+The object hierarchy section is empty because there are no GObjects in the
+libtasn1 API.  With gtk-doc 1.30 onwards if there are no objects then the object
+hierarchy file won't exist, resulting in a failure when building the
+documentation:
+
+| ../libtasn1-docs.xml:39: element include: XInclude error : could not load ../xml/tree_index.sgml, and no fallback was found
