Re: April CCXML: variable not declared in 6_3

Chris,

Thanks for your response.

I understand that there are ways to make the script "pass".

The problem is that the Specification states (8.2.1.1):

"It is illegal to make an assignment to a variable that has not been 
explicitly declared using <var> or a var statement within a <script>."

So even if you change the engine configuration this script breaks the 
CCXML specification.

I believe that it is necessary make this issue clean to avoid future 
problem: either to change the CCXML specification or to use the "STRICT" 
behavior in scripts.

So in fact this issue supports your previous comments regarding variable 
declaration in ECMA script.

Thanks,
Petr
