Clark, this is a slight misrepresentation of what the XSLT 1.1 WD says.

The <xsl:script> *permits* both embedding or use-by-reference.

   <!-- by reference -->
   <xsl:script implements-prefix="uche" language="qname" src="uri"/>

   <!-- by embedding -->
   <xsl:script implements-prefix="evans" language="qname">
     :
   </xsl:script>

The body of the XSLT 1.1 WD specifies no language-dependent features.

A given language binding decides whether embedding, reference,
or both makes sense for that language. It's not stipulated
by the body of the XSLT 1.1 spec.

The Java language binding in appendix C does not allow
embedding, so I'm not sure where Uche's fear of
seeing "embedded Java code" comes from.

(You may argue about the inclusion of shortcut language names
 like "javascript" and "java" which has been discussed at length
 on xsl-list and here, so I'm not talking about this point.
 Assuming language="qname" was the only possibility, there is
 nothing language specific in the body of the draft)

The contracts that the XSLT engine has with the extension
function implementation is completely the responsibility
of each language binding. The language bindings are
relegated to appendices.
