Sorry--I should have been more precise. Try this one instead:

    http://www.w3.org/TR/1999/WD-xslt-19990421

It's the specification of XSLT, which you can reach using the hyperlink in
section 2 of the current WD.

As far as I can tell, <xsl:functions> is a fairly close mapping to <xsl:script>,
and extension functions, plus the new mathematical and string operators, do a
large portion of what <xsl:eval> did. The proof of the pudding would be in
actually translating existing pages that use <xsl:eval> into the new syntax--I'm
not ready to take a position on the relative merits of the tags, since I've
never needed them.
