An untyped atomic value cannot be converted to a QName

Hi Folks,

For xsl:value-of in the below function I am getting this error message:

	An untyped atomic value cannot be converted to a QName or NOTATION
	as required for the result of function f:QName-for-local-name()

Why am I getting that error message?

There are no "untyped atomic values" in xsl:value-of: the argument to
fn:QName, $local-name, clearly has a type -- xs:string.

How do I fix it?

-----------------------------------------------------------
    <xsl:function name="f:QName-for-local-name" as="xs:QName">
        <xsl:param name="local-name" as="xs:string" />
        <xsl:param name="schema" as="element(xs:schema)" />

        <xsl:value-of select="QName((), $local-name)"/>

    </xsl:function>
-----------------------------------------------------------
