Hello!

Yes, a private-scoped rule cannot be referenced in the definition of other  
grammar rules, nor in non-grammar documents. It's only directly accessible  
within its containing grammar. Also, your VoiceXML <grammar /> element  
cannot use as a root a private rule.

However, a private rule which is not used will never match. The same  
applies to public rules.

So, given the following SRGS grammar:

START:--
root $whatever;

$pages = contact | services | portfolio;

$numbers = one | two | three;

$countries = romania | france | germany;

public $people = me | you | her;

public $whatever = $pages | $countries;
--EOF;

$numbers and $people will never match, even if the user says  
"one/two/three" or "me/you/her". This is because the root rule $whatever  
never makes use of $numbers nor $people rules.
