The problem appears to have been fixed in Saxon 9.4.0.6, though I
haven't identified the specific bug fix that cured the problem.

It's actually a NullPointerException within Saxon; oXygen is hiding the
gory detail of the internal error.
As a workaround, use "name(.)" rather than name(). Saxon has trouble
with context-sensitive functions within higher order functions. I'm not
sure of the exact cause and will investigate further. You can track it here:

Hi List,
I'm very interested in XSLT 3.0 and have a question about the function
that returns the function as its return value.
Is it possible to make a such xsl:function?
I tested using the following code in oXygen 14.1 with Saxon 9.4.0.4.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ahf="http://www.yahoo.co.jp/tmakita">
<xsl:template match="root">
<xsl:variable name="slectFunc" as="function(*)"
select="ahf:funcGetChildElementByName('d')"/>
<xsl:copy>
<xsl:sequence select="$slectFunc(.)"/>
</xsl:copy>
</xsl:template>
<xsl:function name="ahf:funcGetChildElementByName" as="function(*)">
<xsl:param name="prmElemName" as="xs:string"/>
<xsl:sequence select="function($a as element()) as element()*
{$a/child::*[starts-with(name(),$prmElemName)]}"/>
</xsl:function>
</xsl:stylesheet>
However Saxon returns following error.
System ID: D:\My Documents\Proj\XSLT-TEST\20130113-func\test.xsl
Main validation file: D:\My Documents\Proj\XSLT-TEST\20130113-func\test.xsl
Engine name: Saxon-EE 9.4.0.4
Severity: error
Description: 0
Is there any workarounds?
