Provide a plain text formatter for the group_audience field that can be used with tokens

Anyone know where I can fix this token replacement to not add the markup as part of the replacement?

I'm moving this because I've gotten no traction in OG (where I guess the token is defined).

Thank you for the information! It looks like OG only offers one formatter :( I will look up how to define a new plain text formatter and submit it to OG as a patch.
The current formatter providing links should probably left as default. How would I define which formatter Tokens is supposed to use?

I've added the default_token_formatter to the og_field_info function (see below) in my site's og.field.inc file but "Group default list" is still the only formatter available to the Group Audience field. I also tried deleting the field and re-adding it.

 function og_field_info() {
   return array(
     'group' => array(
       'label' => t('Group audience'),
       'description' => t('This field stores groups associated with the content.'),
       'default_widget' => OG_AUDIENCE_WIDGET,
       'default_formatter' => 'og_list_default',
+      'default_token_formatter' => 'taxonomy_term_reference_plain',
       // We do not expose the field as entity property, but we provide a
       // separate property making use of the membership entities instead.
     ),
   );
 }

Do you have any suggestions of better ways to form a breadcrumb?
And doesn't OG provide the token definitions that Token can use?

No traction with OG :-( I'm back to ask about the change I made to og_field_info if you see comment #5. Does the 'default_token_formatter' need to be defined anywhere else?

Oh, I think I see the problem, I'm using 'taxonomy_term_reference_plain' in OG... I guess I do need to define a new plain formatter in OG?
