What does XXX stand for in facebook graph's mention tagging format @[ID:XXX:NAME]? -

-

for album description facebook page tagged/mentioned, i'm getting value: "some description text @[page-id:xxx:page-name]"

xxx 3 digit number, can't find info on number stands for. everywhere see @[page-id:page-name] format.

what's best way parse format. should parser expect @[page-id:page-name] , @[page-id:xxx:page-name]?

for might worth, response i'm seeing when opening graph url through chrome browser some description text \u0040[page-id:xxx:page-name], \u0040 instead of @.
