I think it's not quite equivalent, because of the order in which the
attributes are added. In the first, any existing 'host' or 'port'
attributes are added within the xsl:for-each, but then overridden by
the xsl:attribute instructions that add the values from the variables.
In the second, the 'host' and 'port' attributes are given values from
the variables, but then overridden by the attributes copied onto the
element.

I think the first *is* equivalent to:

  <connectionFactory>
     <xsl:copy-of select="@*" />
     <xsl:attribute name="host">
        <xsl:value-of select="$host" />
     </xsl:attribute>
     <xsl:attribute name="port">
        <xsl:value-of select="$port" />
     </xsl:attribute>
  </connectionFactory>

Cheers,
