+<http://qa.openoffice.org/issues/show_bug.cgi?id=115203>: "Issue 113189
+extracted xmlreader from configmgr, to make the former available within URE.
+The xmlreader library is for now considered a private part of URE (cf.
+ure/source/README), for simplicity uses OOO_DLLPUBLIC_XMLREADER-based symbol
+visibility (and thus no symbol versioning), but is of course used from outside
+URE in configmgr. This works as long as its ABI does not change. If it ever
+changes, symbol versioning will have to be added (in some form or other)."
