No it is not.
European Warmblood registries
The origin of the warmblood was the army remounts, they wanted horses that were strong, sane, easy to keep but were somewhat lighter on their feet and with more agility and speed. To get this they crossed the farm working horses (coldbloods) with TB's and Arabians (Hotbloods) and developed a warmblood - mix of hot and cold! In the UK these were refered to as Hunters.
The horses were named after the area they were developed in. Most of the studs being government controlled the type became quite a true type. Warmblood is actually a relitively new term for these horses - they were always refered to by there area of origin.
The modern warmblood can now be bred outside of these areas but to be registered as a particular 'type' still have to be examined by the governing body or their representitive.
I breed New Zealand warmbloods - 1st cross - back to the basics, producing a strong, versatile, sane, active horse that should be able to do any discipline with success.
