It depends what types of 'error' the Rec. is assuming that the
processor might give when confronted with a non-XSLT top-level
element.  I think that the errors it's referring to is simply the
"this isn't a recognised element" error, not all possible errors that
might arise due to those elements.

I think that the (non-normative) XSLT DTD supports this position:

   <!ENTITY % top-level "
      (xsl:import*, (xsl:include | xsl:strip-space |
                     xsl:preserve-space | xsl:output | xsl:key |
                     xsl:decimal-format | xsl:attribute-set |
                     xsl:variable | xsl:param | xsl:template |
                     xsl:namespace-alias
                     %non-xsl-top-level;)*)
      ">

Cheers,

Jeni
