Description: conforming to changes in libxml2/2.14.5
 Some symbols have changed their location, adding includes to find them.
 Also xmlSetStructuredErrorFunc in /usr/include/libxml2/libxml/xmlerror.h now
 expects a second argument with const qualifier: changing
 XMLDocument::errorXPathFunction accordingly.
 The package should be upstreamed.
