It=92s a problem with you stylesheet. XSLT like this is wrong:

    <elem xml:space=3D=93preserve">
        <xsl:attribute name=3D=93attr=94>value</xsl:attribute>
    </elem>

The problem is that there is a text node containing whitespace before the x=
sl:attribute. Text nodes and element nodes are not allowed before xsl:attri=
bute. Normally, these whitespace nodes will be stripped. But since there=92=
s a parent element with xml:space=3D=93preserve=94, the whitespace will be =
kept in this case. I just checked with Saxon and it also reports an error.
