Re: A better way to build a comma-delimited list

Fixed! Thanks Joerg and Tom. I made 2 small changes to the code below:
the "p" variable is not needed; and the substring can start at
position 3 and avoid an extra space at the beginning. Now the output
is perfect. AND the code is simpler. AND I've learned another way to
use xsl:variable. Thanks very much. (This list is amazing.)
