I'm not entirely clear what you do want, but I can't see anything in the
above that could give different results on different processors. If you
write two attributes with the same name, the one written "later" is
guaranteed to win: this is based not on the order of execution, but on the
position of the two attributes in the result sequence. Admittedly the XSLT
1.0 spec isn't very formal on this, this is something we tried to improve in
the 2.0 draft.

Your code does seem a bit convoluted, it could be rewritten as:

> <xsl:template match="fo:*[@it:class]" priority="2">
>   <xsl:variable name="itclass" select="@it:class/>
>
>   <xsl:copy>
>   <xsl:copy-of select="@*"/>

          <xsl:value-of select="."/>
>      </xsl:attribute>
>   </xsl:for-each>
>   <xsl:apply-templates/>
>   </xsl:copy>
> </xsl:template>

Your code achieves this, and is probably the simplest way of achieving it at
XSLT 1.0. In XSLT 2.0 you could write something like

<xsl:copy-of select="@*[every $x in
$cssdocSelect//selector[@it:class=$itclass]/s satisfies name($x) !=
name(.)]"/>

but I don't think I would bother.
