Wrong Required Item Type for variable.. ??

I'm using Saxon 9b

I must have a typo somewhere.. but I don't know where.

Here's the code:

Code:

        
        <xsl:variable name="attrSubTree">
            <xsl:for-each select="$ratttable//TL1Attribute">

                <xsl:variable name="attrName">
                    <xsl:value-of select="."/>
                </xsl:variable>

                <ATTR>
                    <xsl:value-of select="$attrName"/>
                </ATTR>

            </xsl:for-each>
        </xsl:variable>

        <xsl:variable name="namedSubTree">
            <NAMEDBLOCK BLOCK="4">
                <xsl:for-each select="$attrSubTree/ATTR">

                    <xsl:variable name="attrName2">
                        <xsl:value-of select="."/>
                    </xsl:variable>

                    <xsl:if test="string-length($attrName2) > 0">
                        <xsl:if test="count($syntaxSubTree//KEYWD[. = $attrName2]) = 0">
                                <KEYWD>
                                    <xsl:value-of select="$attrName2"/>
                                </KEYWD>
                        </xsl:if>
                    </xsl:if>

                </xsl:for-each>
            </NAMEDBLOCK>
        </xsl:variable>
        
        <!--        
            Dump The Named Attribute SubTree
        
        <xsl:text>&#x0a;</xsl:text>
        <xsl:text>Named Keywords</xsl:text>
        <xsl:text>&#x0a;</xsl:text>
        <xsl:for-each select="$namedSubTree/NAMEDBLOCK/KEYWD">
            <xsl:text>Attribute: </xsl:text>
            <xsl:value-of select="."/>
            <xsl:text>&#x0a;</xsl:text>
        </xsl:for-each>
        -->

The error I get is:

[Saxon-B 9.0.0.6] Required item type of value of variable $attrName2 is document-node(); supplied value has item type xs:untypedAtomic

If I un-comment the Dump code following the variable definition, the error goes away.

If I add a single line <text> prior to the attrSubTree definition, the error goes away.

Code:

        <!--
            First, create a subtree with all the attribute names in the Attribute Table
        -->
        <xsl:text>&#x0a;</xsl:text> <-- Added Line

        <xsl:variable name="attrSubTree">
            <xsl:for-each select="$ratttable//TL1Attribute">

                <xsl:variable name="attrName">
                    <xsl:value-of select="."/>
                </xsl:variable>

                <ATTR>
                    <xsl:value-of select="$attrName"/>
                </ATTR>

            </xsl:for-each>
        </xsl:variable>

If, instead, I add the <text> after the attrSubTree definition, the error does not go away.

Does anyone see something that I'm missing?

Thanks

I fixed the problem (or hid it much better) by removing the <xsl:foreach..$attrAubTree/ATTR..> and writing a template instead.
