Aside from the fact that XTC can be and frequently is MDMA mixed with something else, the form in which it comes (in case of XTC usually a pill) can be very different. In my experience when people explicitly call it MDMA it can be all sorts of things, from crystals to (as the author notes) "MDMA water".
