+Subject: [PATCH] Stop parsing on entities boundaries errors
+
+For https://bugzilla.gnome.org/show_bug.cgi?id=744980
+
+There are times, like on unterminated entities that it's preferable to
+stop parsing, even if that means less error reporting. Entities are
+feeding the parser on further processing, and if they are ill defined
+then it's possible to get the parser to bug. Also do the same on
+Conditional Sections if the input is broken, as the structure of
+the document can't be guessed.
