Hi,
I got some solution about these questions. So I wrote for the mailing

 Until now, no other ways.

if s1.xql will call s2.xql, it does not work if I use the following in
s1.xql:
<a href="http://.../s2.xql?username=jjj&password=12345/> Next </a>

But it can work if I use:
 <a href="http://.../s2.xql?username=jjj&amp;password=12345/> Next </a>

concat() has the same function as string-join().
