This is a FAQ - see, for example, Dave Pawson's FAQ which has a similar
example at

You can do this fine in xslt 1.0 without going to exslt.  Generally, you
use a recursive template.  You pass the string in to the named template
as a parameter.  You test for the presence of a comma, and break the
string into a "first" and a "last" part.  Output the first part.  If
there is a last part, pass it to the same template. Otherwise output
your terminal string, which in your case will be "...". You may need a
bit more logic to output a comma after each bit, depending on whether
you keep the comma when you split the string.
