The function processing the TEI version works if we use the stylesheets as a standalone, but the path the function uses for finding the VERSION file is interpreted als db internal path by eXist-db -- which leads to errors. Thus we remove the TEI function.
The stdheader functionality is not used in SADE's template. To avoid clutter in the resulting HTML we decided to cut out the stdheader completely (instead of just making it invisible in a *.css).
