It's easy enough to find out.  Just hop over to the
www.w3.org web site


and check the DTD.  If we're talking about HTML 4 here, the rule
in the


DTD is quite simple and quite explicit:



<!ELEMENT UL - -
(LI)+                
-- unordered list -->



This says, "A <UL> element may contain one or more
<LI> elements,


nothing else."  Since this is an "element
content" model, white space


and comments are also allowed.  But certainly no other elements
whatever


are allowed, and <SCRIPT> is no exception.

        I would think that scripting was designed

        for exactly these kinds of applications, and I can't imaging why it

        would be disallowed.

Scripting may have been designed for these applications,

but HTML was never really designed for scripting.

The fact is that it IS disallowed.

        but I would like to know if what I am doing is really an error.

        

Yes it is.
