Re: xsl:for-each and xml:space with text-nodes inbetwe

Does someone know what an XSLT 1.0 processor is expected
to do if the immediate child-node of an xsl:for-each is
a whitespace-only text node, which is preserved by xml:space?

<!-- Category: instruction -->
<xsl:for-each
  select = node-set-expression>
  <!-- Content: (xsl:sort*, template) -->
</xsl:for-each>

Should any text-node, regardless if it's whitespace-only or not,
be reported as invalid at such a position?

Using the MSXML .NET Processor, I get the following result:

<?xml version='1.0' encoding='utf-8' ?>
<foo> a b c</foo>

then an error is reported concerning the invalid position of xsl:sort
inside xsl:for-each. I'm confused here.

Was this maybe clarified in the XSLT 2.0 spec?

T:\ftemp>type kasimier.xml
<?xml version="1.0"?>
<foo>
  <bar>b</bar>
  <bar>c</bar>
  <bar>a</bar>
</foo>

T:\ftemp>type kasimier.xsl
<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
        <xsl:template match="/">
                <foo>
                <!-- There's whitespace between xsl:for-each and
xsl:sort. -->
                <xsl:for-each select="/foo/bar" xml:space="preserve">
<xsl:sort /><xsl:value-of select="."/></xsl:for-each>
                </foo>
        </xsl:template>
</xsl:stylesheet>

T:\ftemp>xslt kasimier.xml kasimier.xsl con
