However in the example you gave being the destination of xsl:message output, that interacts with the host environment so is intrinsically implementation specific. How could it be defined? The XSLT spec assumes nothing about the host environment, no assumption that there is for example a file system accessible so it is hard to see how you could define in a way that makes sense on all systems a standard location for any output. Similarly XSLT has a notion of parameters that may be set externally but there is no mechanism specified or specifiable within the XSLT spec as to how they may be set, David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
