RE: RE: [xsl] Help quoting sequence elements

---

I'm all for short-windedness (how's that for malapropistic neologism?), but when I try to substitute:

<xsl:value-of select="for $i in $code-list return concat('''', $i, '''')" 
  separator=", "/> 

<xsl:value-of select="concat('''', $code-list, '''')" 
  separator=", "/> 

my XSLT processor tells me:

XPTY0004: A sequence of more than one item is not allowed as the second argument of concat()

So how would I write the shorter expression?

Thanks.

Incidentally, the expression

for $i in $code-list return $i

is just a long-winded way of writing

$code-list
