I am using a copy pattern that Michael Kay very kindly described
originally for me.
These are the last two templates in my document that do the copying-

<xsl:template match="*" mode="copy">
        <xsl:copy>
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates mode="copy"/>
        </xsl:copy>
</xsl:template>
<xsl:template match="/root/xform">
        <xsl:apply-templates mode="copy"/>
</xsl:template>




Do you need the identity template to be in a mode. In other words, could 
you take out the mode and have it be the default. That way you could 
apply templates here:

...

<xsl:choose>

  <xsl:when test="empty(/root/page)">

    <xsl:apply-templates"/>

  </xsl:when>

  <xsl:otherwise>

    <xsl:apply-templates select="/root/page"/>

  </xsl:otherwise>

</xsl:choose>

...

and just match the page elem (or anything else) to override the default 
copy behavior.

Now I have a template that makes a conditional copy of the
/root/xform/xforms:model/xforms:instance node -

    <xsl:template match="/root/xform/xforms:model/xforms:instance"
mode="copy">
        <xforms:instance>
            <xsl:copy-of select="@*"/>
            <xsl:choose>
                <xsl:when test="empty(/root/page)">
                    <xsl:copy-of select="child::node()"/>
                </xsl:when>
                <xsl:otherwise>
                    <xsl:copy-of select="/root/page"/>
                </xsl:otherwise>
            </xsl:choose>
        </xforms:instance>
    </xsl:template>


Now, what I would like to do is apply a template to that template, so
that I can conditionally replace the
/root/xform/xforms:model/xforms:instance/page/contact node with a custom
node. I tried something like this but I couldnt get it to work, I also
tried playing with priorities and modes but didnt make any progress.

<xsl:template

match="/root/xform/xforms:model/xforms:instance/page/contact"

mode="copy">

        <xsl:choose>

            <xsl:when test="empty(/root/contact)">

                <xsl:copy-of select="."/>

            </xsl:when>   
            <xsl:otherwise>

                <xsl:copy-of select="/root/contact"/>

            </xsl:otherwise>

        </xsl:choose>

</xsl:template>




If you could provide me with details of how to acheive that, I think I
could extend that to other nodes that I want to conditinally replace
with custom nodes -

/root/xform/xforms:model/xforms:instance/page/location
/root/xform/xforms:model/xforms:instance/page//start
/root/xform/xforms:model/xforms:instance/page//end

Thanks very much - Adam Retter
