What about:

<xsl:template match="foo">
    <xsl:when test="ancestor::*/@type = 'a'">
    <xsl:when test="ancestor::*/@type = 'b'">


<xsl:template match="foo[ancestor::*/@type = 'a']">

<xsl:template match="foo[ancestor::*/@type = 'b']">

Would you say the two are roughly equivalent, or are there other
subtle differences?
