> Perhaps try visibility="public" on the function declaration

If I try

<xsl:function name="local:tiny" as="text()" visibility="public">
    <xsl:param name="in" as="xs:string" />
    <xsl:value-of select="$in" />
</xsl:function>

in the calling stylesheet, it is not observed to change the error.

thanks!
