hmm, the xsl package seems to allow/expect PDF images (with suitable
extensions enabled), so I don't understand why 'PDF' isn't a valid
format attribute.
For example, fo/graphics.xsl contains this:

<xsl:param name="graphic.notations">
  <!-- n.b. exactly one leading space, one trailing space, and one 
inter-word space -->
  <xsl:choose>
    <xsl:when test="$passivetex.extensions != 0">
      <xsl:text> PNG PDF JPG JPEG linespecific </xsl:text>
    </xsl:when>
    <xsl:when test="$fop.extensions != 0">
      <xsl:text> SVG PNG PDF JPG JPEG linespecific </xsl:text>
    </xsl:when>
    <xsl:when test="$arbortext.extensions != 0">
      <xsl:text> PNG PDF JPG JPEG linespecific GIF GIF87a GIF89a TIFF 
BMP </xsl:text>
    </xsl:when>
    <xsl:when test="$xep.extensions != 0">
      <xsl:text> SVG PNG PDF JPG JPEG linespecific GIF GIF87a GIF89a 
TIFF BMP </xsl:text>
    </xsl:when>
    <xsl:otherwise>
      <xsl:text> PNG PDF JPG JPEG linespecific GIF GIF87a GIF89a TIFF 
BMP </xsl:text>
    </xsl:otherwise>
  </xsl:choose>
</xsl:param>

which seems to imply that all the above extensions support pdf
inclusions.
