I cannot add a specific attribut to an element using Saxon in XMLSpy

Question

I am transforming a document trying to provide templates to all used elements, and catching the ones I might miss with a "catch all others filter". This works mostly as expected, and I can create a lot of elements with the correct attributes, but I get into trouble with one special attribute - "valign". Everything else works in the supplied code.

I originally included all matches that were supposed to be copied in one template, but here I have tried splitting my xslt match up into different templates, but I still get the same result (which was expected but hey, I had to try...). When I use the XMLSpy debugger, the transform also works.

Source xml snippet:

<?xml version="1.0" encoding="UTF-8"?>
    <content>
                <table tocentry="1">
                    <tgroup align="left" char="" charoff="50" cols="2">
                        <colspec colname="colspec0" colwidth="1*"/>
                        <colspec colname="colspec1" colwidth="1.5*"/>
                        <tbody valign="top">
                            <row>
                                <entry morerows="0" rotate="0" valign="top">
                                    <para>Volume washing fluid</para>
                                </entry>
                                <entry morerows="0" rotate="0" valign="top">
                                    <para>3 dm³</para>
                                </entry>
                            </row>
                        </tbody>
                    </tgroup>
                </table>
    </content>
</dmodule>

I want this to work as an identity transform. The only way I can get around this is to use a "copy-of" when I find a table element.

Error message in XMLSpy (set up with Saxon) is the following: Error evaluating ((attr{xsi:noNamespaceSchemaLocation=...}, ...)) on line 146 column 26 of basics_001.xsl: XTDE0410: An attribute node (valign) cannot be created after a child of the containing element.

I think your approach to output a comment as a child node for attributes not being matched elsewhere is casusing the problem; you will need to use xsl:message to output information about not-matched nodes. Clearly if the rotate attribute results in a child comment output you can't expect to be able to output any attribute node (like valign) afterwards.
