Dan, you're missing the fact that this document clearly points back to a more root document. It indicates that it is a copy of the entry recorded on the Birth Register, Book 44B, Page 5733.
For the purposes of proving that Barack Obama was indeed born in the Republic of Kenya, all that must be done is to gain access to this particular Book and Page, in order to verify that the information on this document is true.
We'd naturally prefer to see something more like a typical US birth certificate with signatures, weight, time of birth, witnesses, etc. But, those things will not be required to establish beyond a shadow of a doubt that Obama was born in Mombassa, Kenya, if this document matches the information in the Birth Register.
Chill, friend. I'm an American, and I'm using American terminology to describe this document. Nothing more.
The Kenyan copy is an exactly copy of the original birth certificate!!
It is NOT a certification of life birth, it is a true copy of the B.C. We don't use all the information of attending nurses/doctors/hospitals, etc. In former years in Europe, at least in Scandinavia, people were born in their homes or also in special private birth clinics owned by midwives. Again my B.C. (1931) looks like this one, and so do the copies later on that I had to submit with my immigration application, and let me tell you, all required papers were very much scrutinized by the U.S. Consular offices abroad before accepted. You had to list every single residential address you had lived on since you were born!!!
