At least someone learned that lesson

The Pope , who is currently dying, has a living will that states that he should be kept on Life-support. Pope John Paul, now being fed through a nasal tube because of his throat problems, effectively wrote his own "living will" last year in a speech declaring some life-extending treatments a moral duty for Roman Catholics. The ailing Pontiff sharply narrowed Catholic guidelines for treating patients nearing death in March 2004 when he described tube-feeding as a normal treatment rather than an extraordinary measure that can be stopped if all hope of recovery fades. This indicates he would want to be kept alive by artificial means even if he fell into a coma or a persistent vegetative state, such as the brain-damaged Terri Schiavo in the United States whose feeding tubes have been removed after 15 years. "The Pope's statement would have to be considered the equivalent of his living will," said Father Thomas Reese S.J., editor of the Jesuit weekly America in New York. "It would be very difficult to unplug him if it came to that." So my question is : what if he doesn't die but stays in a vegatative state? Does that mean they can't chose a new Pope till then? Will anyone else assume the post until a new pope is chosen? Does anyone know?
