/**
*
* Running Xalan extension functions on Android is problematic:
*
* http://stackoverflow.com/questions/10579339/is-it-possible-to-call-a-java-extension-function-from-xalan-on-android
*
* and generating the XSL FO via Xalan + extension functions
* is a bit slow,
* so this uses TraversalUtils to generate XSL FO output
* without any need for Xalan or XSLT.
*
* The intent is that this mechanism will ultimately
* completely replace the Xalan based approach, at which
* point docx4j will no longer be dependent on Xalan
* (the XSLT included in Oracle's java is sufficient for
* our mc pre processor)
*
* We could use a simple JAXB model of XSL FO,
* or org.w3c.dom to construct the XSL FO document.
*
* This implementation uses org.w3c.dom, since
* that is easiest based on existing code.
*
* This class might be neater if it used CompoundTraversalUtilVisitorCallback,
* but it would be less obvious what is going on.
