Not really an XSLT issue, but if you don't prefix the end comment tag with a
JavaScript comment delimiter, interpreters will treat it as a pre-decrement
operator, which can generate unexpected errors.  So the last line before the
end script tag should look like:

//</xsl:comment>

Could you put the comment tags (literal, not xsl:comment) inside the CDATA
block, or would that still cause the processor to ignore the contents?

In practice, I no longer see the point of wrapping script code in comment
tags.  IIRC, it's only needed for browsers that don't understand the script
tag (as opposed to not recognizing JavaScript, or having scripting disabled
via an option setting).  How many people are actually using such beasts
these days?

cheers,
