Veganism when used by it's self is not clearly defined as seperate from vegetarianism.
"Dietary vegans (or strict vegetarians) refrain from consuming animal products, not only meat but, in contrast to ovo-lacto vegetarians, also eggs, dairy products and other animal-derived substances. The term ethical vegan is often applied to those who not only follow a vegan diet, but extend the vegan philosophy into other areas of their lives, and oppose the use of animals and animal products for any purpose.[4] Another term used is environmental veganism, which refers to the avoidance of animal products on the premise that the harvesting or industrial farming of animals is environmentally damaging and unsustainable.[5]" http://en.wikipedia.org/wiki/Veganism
PS: Also if you actaully read the link: "Jains are either lacto-vegetarians or vegans."
