Yes, this is true. On the other hand, the internet works because most 
systems are tolerant. Some time ago I implemewnted vcard PHOTO. You 
would be surprised how many things can be wrong. But as a programmer I 
try to make things work by tolerating errors as long as they do not 
break anything. Therefore my question if type='available' does break 
something. Obviously it breaks servers (client connections) at schema 
validation time. I question strict schema validation anyhow because it 
contradicts the IETF's be-tolerate-and-conservative claim. But there are 
also valid arguments for strictness. So, lets shoot them in this case.
