+Subject: [PATCH] Remove the access to entities 'checked' private symbol for
+ libxml2 2.11.0
+
+Since version 2.11.0, some private symbols that were never intended
+as public API/ABI have been removed from libxml2, therefore the field
+'checked' is no longer present and raptor fails to build in this
+scenario.
