The first does not give the identity template stylesheet an opportunity to intervene on a particular attribute node being pushed at the stylesheet. This would be done with a:

Note the use of the "," instead of "|" as this apparently prevents the need for the processor to arrange the nodes in document order. Not a big savings, but a savings nonetheless.
We all learn a lot from Mike!

Michael --
So you're saying that you prefer
<xsl:template match="*"> <xsl:copy> <xsl:copy-of select="@*"/> <xsl:apply-templates select="node()"/> </xsl:copy> </xsl:template>
to
<xsl:template match="@*|*"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template>
Those are different, Syd, so not interchangeable.
The first does not give the identity template stylesheet an opportunity to intervene on a particular attribute node being pushed at the stylesheet. This would be done with a:
<xsl:template match="@abc">.....
for the cases where attribute processing is minimal, right? May I ask if that is because it's more efficient, more elegant, more XSLT-ish, or just personal preference?
Thanks!

<xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template>
