Xalan-C++ version is a robust implementation of the W3C Recommendations for XSL Transformations (XSLT) and the XML Path Language (XPath). It works with the Xerces-C++ XML parser.
The Xalan-C++ project creates and distributes a standard XSLT library and a simple Xalan command-line utility for transforming XML documents. This is a dependency for brewtarget. OK?
