[vpim] Comments: draft-ietf-vpim-vpimdir-09.txt

Hi Greg,

I just have a few comments to make about this draft, which mainly relate 
to the inclusion of additional matching rules into the Attribute 
definitions. I've only recently joined this list, so please excuse me if 
these topics have been discussed before.

> 3.1 vPIMTelephoneNumber

Based on the nature of this attribute, it probably wouldn't hurt to 
include a substrings matching rule of caseIgnoreSubstringsMatch. This 
would enable operatins such as: "Searching for all phone numbers with a 
sub address of 12", to be possible.

Your comment suggests that the Syntax of this attribute is a 
DirectoryString, however the OID and matching rule indicate an IA5String.

With the inclusion of non-standard information it may be worth adding a 
substrings matching rule. This may come in handy for directory 
administrators attempting to identify all entries that contains 
non-standard information.
Note: This could also apply to section 3.8 as well.
