Description
Some JavaScript code uses Element.getAttribute() or Element.setAttribute() to access data that is available through a DOM object property. In general, the properties should be preferred as they are always normalized values and typed. The getAttribute()/setAttribute() are an abstraction over the serialized text representation.

I agree that we should prefer DOM properties but we need to be aware of differences and caveats (see comparison). For example href is quite tricky because as a DOM property it's always a full URL, even if the attribute contains a relative URL or just a # and of course on IE it doesn't work that way.
