Hi Jack,

Yes, what you are describing is a "literal result element as
stylesheet". It is effectively shorthand for an XSLT stylesheet with a
single template rule, matching the root node.


<html xmlns:xsl="http://www.w3.org/1999/XSL/Transform"   xsl:version="2.0">
... do your thing ...

to an XSLT processor, when provided as a stylesheet, is the same as

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

  <xsl:template match="/">
    <html> ... do your thing ... </html>


This was (one imagines) meant to be a convenience, but it's not used
much TMK. (I may have used it ... once?) This is probably because,
with only one template, such a stylesheet can never execute more than
a simple "pull"; as soon as you need another template you have to
build it out. It may also be at least as confusing to the newcomer as
it is useful. (Namespaces anyone?)

Cheers, Wendell

means that the file supplied as the stylesheet document did not have
xsl:stylesheet or xsl:transform as its root. In fact more specifically I think
it means the local name of the root element was not "stylesheet" or
"transform" - you get a different message if only the namespace is wrong.
