Thanks. What happens to the <?xml?> PI, though?

A PI can exist anywhere in an XML document, not just at the start,  
and a PI can contain most character sequences. So, I assume that all  
nodes must be able to contain PI nodes (just like they can contain  
normal element nodes.).

If all nodes can contain PI nodes, then why does the document node  
not contain the PI node just like normal?
