That looks fine. Doesn't it work?

The same rules apply for the content of xsl:processing-instruction as
do for xsl:comment, yes -- you can't create nodes aside from text
nodes within them. But that's all you're doing in the above --
creating text -- so what you have should be fine. If you tried to do:

  <xsl:processing-instruction name="xml-stylesheet">
    <xsl:attribute name="href">
      <xsl:value-of select="html:html/html:head/html:link[@rel='stylesheet']/@href"/>
    </xsl:attribute>
    <xsl:attribute name="type">text/css</xsl:attribute>
  </xsl:processing-instruction>

*that* would be an error.

Cheers,
