Hi Mark,

Not quite: you can override all default rules together. An identity
transform is given in the XSL spec, section 7.5:

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

Rather than modify it, supplement it with a template specifically for that
element where you want the test and possible new child:

<xsl:template match="yourelement">
    <xsl:apply-templates select="@*"/>
    <xsl:if test="not(child)">
      <child><!-- whatever you like --></child>
    <xsl:apply-templates select="node()"/>

>and finally, can you modify this to show testing the presence of an

<xsl:template match="yourelement">
    <xsl:if test="not(@yourattribute)">
      <xsl:attribute name="yourattribute">
    <xsl:apply-templates select="@*|node()"/>

Note that I haven't tested this stuff, but I think it'll do what you want.
