So, Dave was talking about outlines

which of course meant I started thinking about otlml. Which, in turn, made me think about the opml2otlml stylesheet I still haven't written. That got me thinking that it would be cool if you could do this:




&lt;xsl:copy-of select = "transform(document($xml),document($xsl))" />

Then it occurred to that you might be able to do the same thing like this (untested) :




&lt;xsl:for-each select = "/xpath/to/some/xref[@style != '']">



 &lt;xsl:variable name = "style" select = "@style" />



 &lt;xsl:include href = "$style" />



&lt;/xsl:for-each>







...







&lt;!-- would really be a choose... -->



&lt;xsl:if test = "@style">



 &lt;xsl:apply-templates>



  &lt;xsl:apply-templates select="document($uri)/$xpath"/>



 &lt;/xsl:apply-template>



&lt;/xsl:if>

So now I'm wondering if I really need to add an include element to the DTD...
