<voice> tag w/i <choice> issue

[tloring]

The <voice> tag w/i a choice tag is generating an bad fetch error. The validator does in fact give an error, however, <voice> should be a valid child tag of <choice> (per plum online reference and other sources). Or am I missing something? Thanks.

Code: Select all

Validation Results: 
Error at  line 12, char 79
  Message: Element 'voice' is not valid for content model: '(#PCDATA|grammar)*'

Code: Select all

<?xml version='1.0'?>
<vxml version="2.0" application="global.xml">

<menu id="mainmenu">
  <prompt>
  <voice name="audrey">
  Press 1 to record.
  Press 2 for help.
  Press 3 to end call.
  </voice>
  </prompt>
  <choice dtmf="1" next="#record"><voice name="audrey">Record</voice></choice>
  <choice dtmf="2" next="#help">Help</choice>                 
  <choice dtmf="3" next="#end">End Call</choice>              
</menu>

Hi Tom:

Looks like you've uncovered a mistake in the IVR Programmers guide! Shame on you!

jk, thanks for alerting us...according to the w3c official VXML DTD, only IVR grammars are allowed within choice tags.


kind regards,

We've updated the IVR PRM to reflect this change. Thanks for the heads up, Tom!

That's what I get for RTFM...should have just looked at the spec

Hmm...yes, you're right...then I've also uncovered a mistake in "Definitive VoiceXML" (Adam Hocek, David Cuddihy), which lists <voice> as a child as well in the tag summary.

I realize now I didn't really need it there - I was thrown off by the documentation. If I want to use the <choice> contents for the prompt, I just need to <enumerate> them w/i the <prompt> in which I can set the <voice> legally.

Code: Select all

<menu id="mainmenu">
  <prompt>
  <voice name="audrey">
  <enumerate>Press <value expr="_dtmf"/> to <value expr="_prompt"/><break size="small"/></enumerate>
  </voice>
  </prompt>
  <choice dtmf="1" next="#record">Record</choice>
  <choice dtmf="2" next="#help">Help</choice>
  <choice dtmf="3" next="#end">End Call</choice>
</menu>

So, all is good.
