title: Should I learn XML 1.0 or XML 1.1?
body: <p>I know that a well-formed XML 1.1 is not necessarily a well-formed XML 1.0 and vice-versa.</p>
  
  <p>I want to learn xml formally and i was wondering whether i should learn XML 1.0 or XML 1.1? I mean would it be more effective to learn XML 1.0 or would it be more effective to learn XML 1.1?</p>
  
  <p>I mean of course I know its best to read them both.. but i really only have the time to read one of them, so which would be "better" (more useful to me, me as in the average programmer)?</p>
