CodeSynthesis XSD is an open-source XML Schema to C++ data binding compiler that uses Xerces-C++ as the underlying XML parser. Provided with an XML instance specification (XML Schema), XSD generates C++ classes that represent the given vocabulary as well as parsing and serialization code. You can then access the data stored in XML using types and functions that semantically correspond to your application domain rather than dealing with direct representations of XML such as DOM and SAX.

Xalan-C++ is an open-source XSLT processor for transforming XML documents into HTML, text, or other XML document types. It implementes the W3C recommendations for XSL Transformations (XSLT) and the XML Path Language (XPath) and is based on Xerces-C++.

XQilla is an open-source XQuery and XPath 2.0 implementation based on Xerces-C++. It implements the DOM 3 XPath API and conforms to the W3C proposed recommendation of XQuery and XPath 2.0.

XML Security for C++ is an open-source implementation of the XML Digital Signature and Encryption specifications and is based on Xerces-C++. The library also provides support for serializing XML in the canonical form.

Shibboleth is an open source Web Single Sign-On and Federation implementation that supports the SAML 2.0 and SAML 1.1 standards, among other capabilities. The Service Provider and underlying OpenSAML library use Xerces-C++.
