Subject Re: C2 with saxon
Date Tue, 11 Jun 2002 21:20:24 GMT
You can use Saxon's -X option to force saxon to use Xerces as the xml
parser. For command line it's something like:

java com.icl.saxon.StyleSheet -x org.apache.xerces.parsers.SAXParser

I don't know how to translate it to Cocoon instructions
