What are the advantages

What are the advantages of the using XHTML rather than HTML?

Theoretical or practical? Real or Pretend XHTML? Basically extensibility is the answer and they are two very different languages real XHTML is nothing like HTML other than it mimics the elements. I am one of the rare people that serves real XHTML to browsers that can accept ‘application/xhtml+xml’.
