 Note(s):  metadata ignored by both LaTeX and the source compiler
 Code:  source code ignored by LaTeX
 Listing(s):  source code included by LaTeX in technical documentation
 Tex:  documentation and markup ignored by the source compiler

The XML is styled by CSS.  
A Combined Viewer would display all elements.
A Code Viewer would ignore notes and tex. 
A Tex Viewer would ignore notes and code. The following TeX stub allows 
the rendered file to be compiled by MikTex
