[jdom-interest] Why no Node interface?

[Kenneth Lee]

Althought it may make the API a bit more heavier (and more like DOM), I
still think that having Element and Attribute (or other node types)
implement the same Node interface is a good idea. If so then I can eliminate
many of my instanceof checks to distinguish between Element and Attribute.

e.g.  ((Node) obj).getText();

Is it the only way for using instanceof?
