I just noticed that the example-input for the first problem isn't clear
maybe. I'm talking about only entering "#".
 
Thank you and kind regards,

Subject: Vxml grammar with termtimeout=0s. How should the intrepeter
react?



Hello, 

I've written a small vxml-grammar and the product on which we use it is
not reacting like I think it should. Could someone confirm or correct
what the expected behaviour should be according to vxml 2.1?

This is the grammar (I know it could be written better :)): 

<?xml version="1.0" encoding="UTF-8"?> 

<grammar xmlns="http://www.w3.org/2001/06/grammar" xml:lang="en-US" 
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
         xsi:schemaLocation="http://www.w3.org/2001/06/grammar 
 
http://www.w3.org/TR/speech-grammar/grammar.xsd
<http://www.w3.org/TR/speech-grammar/grammar.xsd> " 
         version="1.0" mode="dtmf" root="NatRegNumber"> 

<rule id="digit" scope="public"> 
        <one-of> 
                <item>0</item> 
                <item>1</item> 
                <item>2</item> 
                <item>3</item> 
                <item>4</item> 
                <item>5</item> 
                <item>6</item> 
                <item>7</item> 
                <item>8</item> 
                <item>9</item> 
        </one-of>       
</rule> 

<rule id="NatRegNumber" scope="public"> 
<!--A National registry number is permitted, or not input.--> 
<one-of> 
        <item> 
                <item repeat="1-11"> 
                        <ruleref uri="#digit"/> 
                </item> 
                <item repeat="0-1"> 
                        # 
                </item> 
        </item> 
        <item>#</item> 
</one-of> 
</rule> 

</grammar> 


Termtimeout=0s and there is no termchar. Interdigittimeout and timeout
are 3s. The interpreter doesn't end immediately after the '#', but waits
the interdigittimeout. Shouldn't it end immediately?

------------------------------------- 
Another one. I've written the following grammar: 

\d{11}? 

Termchar is '#' and termtimeout > 0s. If I only enter '#' on the phone,
shouldn't it pass as a valid input because I've entered dtmf input, so
that the no-input can't be thrown (according to the examples in the
specification). The input actually passes the grammar as I allow empty
input. Am I correct or wrong?

Thank you for your help and kind regards, 

Michel
