RE: Suppressing attributes while merging

You can take advantage of the fact that if you call <xsl:attribute>
twice for the same element, and the two attributes have the same name,
the second one overwrites the first. The same is true if you create the
attributes using <xsl:copy> or <xsl:copy-of>

So just do:

<xslt:copy-of select="$first2/@*" />
<xslt:copy-of select="$first1/@*" />
