[SECURITY] Fedora 28 Update: mingw-xerces-c-3.2.1-1.fc28

Xerces-C is a validating XML parser written in a portable subset of C++. Xerces-C makes it easy to give your application the ability to read and write XML data. A shared library is provided for parsing, generating, manipulating, and validating XML documents. Xerces-C is faithful to the XML 1.0 recommendation and associated standards (DOM 1.0, DOM 2.0. SAX 1.0, SAX 2.0, Namespaces).
