I found
You cant alter the content from a script, but you can use your variables in such a way that it almost simulates the desired
  behaviour. A wml page with variable references only, will be dynamical, although you cant assign wml code to your variables.
  Your tags can be variable references such as <a href="$(var1)">$(var2)</a> 
  Even your images could probably be variable references, havent tried that myself though.

Elsewhere I found:
<?xml version="1.0"?> 
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml"> 
 
<wml> 
 
	<card id="SSN" title="SSN:">
		<do type="accept" label="Results">
			<go href="WMLScriptExample.wmls#validateSSN($(SSN))"/>
		</do>
		<p>
		Enter SSN: <input type="text" name="SSN"/>
		</p>
	</card>

	<card id="Results" title="Results:">
	<p>
	You entered:<br/>
  SSN: $(SSN)<br/>
	</p>
	</card>

</wml> 
extern function validateSSN(SSN)
{
	if (String.length(SSN) != 9)
	{
		WMLBrowser.setVar("SSN", "Error: String must be 9 digits long.");
	}

	WMLBrowser.go("WMLScriptExample.wml#Results");
};

This looks like use of function validateSSN($(SSN)) as an event handler
while <a href="$(var1)">$(var2)</a> allows you to construct card

So I think it is fair to say that the WAP DOM is limited (no mouse over etc.!)
but WMLSCript understands it.

I see book(s) from WROX in July

So in general description is excellent
I think we need to get Oh implementing. Looks fun
