 * This sample uses XSLT (and Xalan) to 
 * produce HTML output.  (There is also
 * HtmlExporterNonXSLT for environments where 
 * that is not desirable eg Android).
 * 
 * If the source docx contained a WMF, that
 * will get converted to inline SVG.  In order
 * to see the SVG in your browser, you'll need 
 * to rename the file to .xml or serve
 * it with MIME type application/xhtml+xml
