Saxon

The essence of the problem is this code:

   @<xsl:variable name="product-type" as="xs:string" select="."/>

        <xsl:result-document href="{$product-type}-result.xml">

            <root>

                <xsl:stream href="{$input-uri}">

                    <xsl:for-each select="*/product[@type = $product-type]">

                        <xsl:copy-of select="."/>

                    </xsl:for-each>

                </xsl:stream>

            </root>

        </xsl:result-document>@

where Saxon is trying to determine the streamability of the variable $product-type by referencing the streamability of the corresponding variable declaration, which has not been assessed because it does not appear in streamable code.
