You +will need the ACE library[1] installed in order to build and run this +example. + +[1] http://www.cs.wustl.edu/~schmidt/ACE.html + +The example consists of the following files: + +library.xsd + XML Schema which describes a library of books. + +library.xml + Sample XML instance document. + +library.hxx +library.cxx + C++ types that represent the given vocabulary as well as data + representation stream insertion and extraction operations.
