Hi,

phonedigit is used in an extension rule.

   extension            = ";ext=" 1*phonedigit

if the original definition is correct, I think a following
description is valid.

tel:1234;ext=;phone-context=example.com

May an extension number be an empty string?

At the very start what is the reason why visual-separator became an 
optional rule?
according to the document history,

RFC2806
   phonedigit            = DIGIT / visual-separator

draft-ietf-iptel-rfc2806bis-01
   phonedigit            =  DIGIT [ visual-separator ]
   phonedigit-hex        =  HEXDIG [ visual-separator ]

draft-ietf-iptel-rfc2806bis-02
   phonedigit            =  DIGIT / [ visual-separator ]
   phonedigit-hex        =  HEXDIG / "*" / "#" / [ visual-separator ]

Anydody know the intent of this fix?

Regards,
Shinji
