Re: [xsl] Error message saying doc is not well formed, has >1 top level element

[Michel Hendriksen <michel.hendriksen@xxxxxxxxx>]

This will generate two <foo/> root elements which is not allowed/well
formed as stated.

But indeed the bar thing would also be bad...

Looks like it can see that you are at the root and create two
elements. If you do it in different templates it doesn't know.
But then only the second time and only when standalone is on. Might be
soemthing in the specs.

<?xml version="1.0"?>
 <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">

 <xsl:output standalone="yes"/>

 <xsl:template match="/">
   <xsl:call-template name="tempa"/>
   <xsl:call-template name="tempa"/>
 </xsl:template>

 <xsl:template name="tempa">
   <bar/>
   <bar/>
 </xsl:template>

</xsl:stylesheet>

into an XML parser, the error could conceivably relate to the result document,
and the point at which it is reported could be random because of output
buffering. However, unless you're doing this, I wouldn't expect to see this
error reported on a result document.
