Yes, elements in the prolog such as comments and PIs do have sibling 
relationships. More importantly, comments, processing instructions, 
and text nodes inside the root element (at whatever level) have 
sibling relationships. Siblings aren't just for elements.  I agree 
that  getNextSibling and getPreviousSibling don't make a lot of sense 
for Document, but they do make sense for Element, Comment, Text, and 
ProcessingInstruction.

Here I'm running into a problem with Java's lack of multiple 
inheritance. I can't break out separate classes for ParentNode and 
ChildNode when Element needs to be both. :-(
