The use of the SAXParserFactoryImpl when setting the XMLResolver throws the following exception:

[FactoryConfigurationError: Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found]
   IKVM.NativeCode.sun.misc.Unsafe.throwException(Object thisUnsafe, Exception x) +33
   sun.misc.Unsafe.throwException(Exception t) +37
   java.lang.Class.newInstance0(CallerID ) +744
   java.lang.Class.newInstance(CallerID ) +104
   net.sf.saxon.trans.DynamicLoader.getInstance(String className, ClassLoader classLoader) +180
   net.sf.saxon.Configuration.makeURIResolver(String className) +73
   net.sf.saxon.trans.XmlCatalogResolver.setCatalog(String catalog, Configuration config, Boolean isTracing) +237
   _Default.Page_Load(Object sender, EventArgs e)

This is a class loader issue, where the class is not available in the default ClassLoader. The solution in the DynamicLoader class is to add the SAXParserFactoryImpl class to the list of known classes.
