Facteur de Chevaux de Selle et Cairo

Can anyone explain to me what the studbook Facteur de Chevaux de Selle is?

Also if anyone knows anythin about Swedish stallion Cairo offspring in France please let me know. He stood at stud in France between 1998-2004 and is supposed to have covered around 40-50 mares.

Some stranger stallions are "facteur de selle français", most of them are not.
Rubinstein was facteur de selle français, so my mare, (from Rubinstein, West. and a mare , selle français), is 'selle français" and not Westphalian like Rubinstein. in fact, it is an authorization from France, for stallions who gave a lot of good products to product horses in the french studbook, my mare is wearing a baby from a new stallion, an oldenburg one, he is not (facteur de selle français), so the foal will be " cheval de selle", he could be selle français if he is a good winner in the breeding french tests.
Excuse me for my bad english, I hope you'll understand my explanations

And to make it easy, there is two different category of "Facteur de selle Français" you have the "SFA" and the "SFB".

In the SFA you have 100% french mare and 100% french stallions, plus the stallions of foreign country who have been graded "SFA" like Heartbreaker regarding their good production/results and a french mare SFA and a foreign country SFA will give a SFA foal.

In the SFB you have all the other stallions of foreign country who can breed for SF in SFB (they could be graded SFA after. Then the production will change to SFA) but they are usually more young.

So to breed a SF you need a stallions SFA or SFB

Thankyou so much both of you

What made me so confused is the fact that at the Haras Nationaux website Cairo is named as breeding in facteur de selle, Iowa in SFA and Quite Easy in SFB. SFA and SFB I new about but I had never heard about the facteur de selle.

ps I need to practice my french and am about to start reading the classic Les tros mousquetaires in french (no cheeting) so maybe one day soon I start asking questions in good old french
