It doesn't seem to work for me. I had to put this line right after the xls namespace declaration line. Now it drops an "unknown error".
To reproduce the error, follow these steps: 1. download the 3 attached files into one directory 2. extract the DocBook xslt files into a subdirectory called "docbook-xsl-1.76.1" 3. open the file called "MathML_XSLT_teszt.xml" in a browser (I use FireFox) 2012/6/20 Bob Stayton <[email protected]> > Hi Zoltán, > I assumed you were developing a customization layer of DocBook XSL.
