What championship belts actually count when talking about breaking Flair's 16-title record?

[Emperor Smeat]

All this talk about title records and Flair's record of 16 titles had me thinking of which belts would actually qualify as being a "major" title and worthy enough to be considered in the totals.

Does the TNA title actually count post-NWA years or is it more of an ROH/old ECW title of being a smaller belt in status?

It can't be just any belt or else Lawler basically doubles Flair's total alone with his Memphis championships.

So far everyone agrees that the NWA, WWF/E, and WCW championship counts for official total but do any of the Indy or foreign promotion titles officially count?
