No browser currently supports parent-child-sibling type navigation,
because HTML doesn't make it easy to support such structures. HTML+, with
its containerized paragraphs and hierarchic sections, is a great leap
forward in that direction, so I hope very much that this kind of
facility will soon start to appear. When you're implementing it chaps,
please don't forget that it would be useful to say not just 'get me the
nth child' but 'get me the nth child which is a FOO',. For example:
- go to the next child <changed> tag
- go to the <H1> of which this paragraph (somewhere inside a H4) is the
  direct descendant
- go to the next <h2> inside this <H1>
