How was the Buddha Jayanti edition of the Tripitaka derived?

I've read that the three Theravada countries Sri Lanka, Thailand and Myanmar all three have their own version of the Tripitaka. I've also read that in 1956 they held the Sixth Buddhist convention with the goal of creating one standard edition of the Tripitaka, called the Buddha Jayanti-edition. The Dutch version of the Wikipedia page on the Pali canon claims that > The Buddha Jayanti-Edition, however, was composed by the most distinguished monks of the three main Buddhist countries and is considered the most correct version (original wiki page [here](http://nl.wikipedia.org/wiki/Pali-canon#Moderne_versies) , English translation [here](https://translate.google.com/translate?sl=nl&tl=en&js=y&prev=_t&hl=nl&ie=UTF-8&u=http%3A%2F%2Fnl.wikipedia.org%2Fwiki%2FPali-canon)) I was wondering if this is true. How do they know that the Buddha Jayanti-edition is the most correct version? What exactly are the differences between the 3 Tipitaka versions and how did the monks resolve them?
