The xsl:stylesheet element is always
            the top-level element of an XSLT stylesheet. The
            name xsl:transform may be used as a synonym.
         
The following attributes may be specified:
| 
                   version  | 
               
                   Mandatory. A value other than "1.0" invokes forwards compatibility mode.  | 
            
| 
                   saxon:trace  | 
               
                   Value "yes" or "no": default no. If set to "yes", causes activation of templates to be traced on System.err for diagnostic purposes. The value may be overridden by specifying a saxon:trace attribute on the individual template.  |
