It’s a problem with you stylesheet. XSLT like this is wrong:

    <elem xml:space=“preserve">
        <xsl:attribute name=“attr”>value</xsl:attribute>
    </elem>

The problem is that there is a text node containing whitespace before the xsl:attribute. Text nodes and 
element nodes are not allowed before xsl:attribute. Normally, these whitespace nodes will be stripped. But 
since there’s a parent element with xml:space=“preserve”, the whitespace will be kept in this case. I just 
checked with Saxon and it also reports an error.
