Hi Florent,

I've aways considered the "Modified Identity" pattern to be the
identity template that walks the following sibling axis:

<xsl:template match="node()">
	<xsl:copy>
		<xsl:copy-of select="@*"/>
		<xsl:apply-templates select="node()[1]"/>
	</xsl:copy>
	<xsl:apply-templates select="following-sibling::*[1]"/>
</xsl:template>

(see http://biglist.com/lists/xsl-list/archives/200612/msg00373.html)

These are two definite patterns - what is the concencus of the list is
for the names of the two types?

I know them as "identity" and "modified identity"... (the latter not
being great if a third type comes along, but acceptable if it's
already gained widespread acceptance)


cheers
