Is there an easy way (or any way at all) to identify the type of the
node being processed?

Yes, there is a way for all seven kinds of node. This is described on pages 188-189 of the paper rendition of our XSLT book published by Prentice Hall, or pages 192-193 of the Tenth Edition of the PDF rendition of our book that we publish (Eleventh edition, last for XSLT 1.0, coming hopefully soon!):

    <xsl:when test="self::book:fig">      <!--display caption-->
      <xsl:text>book:fig: </xsl:text><xsl:value-of select="."/>
    <xsl:when test="self::*">                  <!--an element-->
      <xsl:text>Element: </xsl:text><xsl:value-of select="."/>
    <xsl:when test="self::text()">              <!--show text-->
      <xsl:text>Text: </xsl:text><xsl:value-of select="."/>
    <xsl:when test="self::comment()">      <!--reveal comment-->
      <xsl:text>Comment: </xsl:text><xsl:value-of select="."/>
    <xsl:when test="self::processing-instruction()">   <!--pi-->
      <xsl:text>PI: </xsl:text><xsl:value-of select="."/>
    <xsl:when test="count(.|/)=1">                  <!--root-->
      <xsl:text>root </xsl:text>
               <!--specific namespaced-unqualified attribute-->
    <xsl:when test="count(.|../@version)=count(../@version)">
      <xsl:text>version attribute </xsl:text>
                  <!--specific namespace-qualified attribute-->
    <xsl:when test="count(.|../@book:ref)=count(../@book:ref)">
      <xsl:text>book:ref attribute </xsl:text>
                       <!--any namespace-qualified attribute-->
    <xsl:when test="count(.|../@book:*)=count(../@book:*)">
      <xsl:text>book:* attribute </xsl:text>
                                           <!--any attribute-->
    <xsl:when test="count(.|../@*)=count(../@*)">
      <xsl:text>attribute </xsl:text>
                                      <!--specific namespace-->
    <xsl:when test="count(.|../namespace::xsl)=
      <xsl:text>XSL namespace </xsl:text>
                                           <!--any namespace-->
    <xsl:when test="count(.|../namespace::*)=
      <xsl:text>namespace </xsl:text>

I hope this helps.
