Have you also tried the XPath function doc() ?

Both the latest internal draft of the XSLT 3.0 spec in
https://www.w3.org/XML/Group/qtspecs/specifications/xslt-30/html/#dynamic-xpath
as well as the official https://www.w3.org/TR/xslt-30/#element-evaluate say
about the function signatures in the context of dynamic XPath evaluation
using xsl:evaluate: "Note that this set deliberately excludes XSLT-defined
functions in the standard function namespace".
Based on that I would expect the XSLT "document" function not to be
available in dynamic XPath evaluation using xsl:evaluate. So I wrote a test
case doing
<xsl:stylesheet version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:fn="http://www.w3.org/2005/xpath-functions";
xmlns:math="http://www.w3.org/2005/xpath-functions/math";
xmlns:array="http://www.w3.org/2005/xpath-functions/array";
xmlns:map="http://www.w3.org/2005/xpath-functions/map";
exclude-result-prefixes="array fn map math xs">
<xsl:output method="xml"/>
<xsl:template name="main" match="/">
<xsl:sequence
select="
let $f := function-lookup(xs:QName('fn:document'),
1)
return
if (exists($f)) then
$f('')
else
'not found'"/>
<xsl:variable name="path" as="xs:string">
let $f := function-lookup(xs:QName('fn:document'),
1)
return
if (exists($f)) then
$f('')
else
'not found'</xsl:variable>
<xsl:evaluate xpath="$path"/>
</xsl:template>
</xsl:stylesheet>
and expected that to return the stylesheet code for the xsl:sequence and
'not found' for the xsl:evaluate.
However, only Exselt gives me that result, both Saxon 9.7 EE as well as
Altova XMLSpy return the stylesheet code twice which seems to indicate they
make the 'document' function available to xsl:evaluate. Isn't that a bug? Or
does the spec need to allow it if an implementer wants to go beyond pure
XPath support?
