Local rule references in vxml 2.0

Hello. Question is whether local rule references in inline grammars are allowed in vxml 2.0 or not.

Section 3.1.1.4 says:

The following are the forms of rule reference defined by [SRGS] <file:///D:\IMS\VXML\Voice%20Extensible%20Markup%20Language%20%28VoiceXML%29%20Version%202.0.htm#ref_SRGS>  that are not supported in VoiceXML 2.0.

*	Local rule reference: a fragment-only URI is not permitted. (See definition in Section 2.2.1 of [SRGS] <file:///D:\IMS\VXML\Voice%20Extensible%20Markup%20Language%20%28VoiceXML%29%20Version%202.0.htm#ref_SRGS> ). A fragment-only URI value for the src attribute causes an error.semantic event.

But two examples in the spec are using local rule references in the inline grammars (sections 3.1.1.1 and 3.1.1.2).

So, is it allowed to use local rule references in the inline grammars (it is said that fragment-only URI value for the src attribute causes an error.semantic event)?

Is this example from the SRGS valid:

 
<grammar mode="dtmf" version="1.0" 
         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"
         xmlns="http://www.w3.org/2001/06/grammar">
 
<rule id="digit">
 <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="pin" scope="public">
 <one-of>
   <item>
     <item repeat="4"><ruleref uri="#digit"/></item>
     #
   </item>
   <item>
     * 9
   </item>
 </one-of>
</rule>
 
</grammar>

 

 

And one more question: If it is allowed to use local rule references in inline grammars, if the local reference contains unavailble rule name (e.g. rule does not exist in this grammar), what error event will occur?
