document.head, document.body to attach scripts

Question

I have often used, and seen recommended, dom-access structures like this for adding content to pages dynamically:

loader = document.createElement(\'script\')         


        

Answer 1

document.body is part of the DOM specification, I don't see any point why not to use it. But be aware of this:

In documents with contents, returns the element, and in frameset documents, this returns the outermost element.

(from https://developer.mozilla.org/en/DOM/document.body)

document.head currently isn't defined in any DOM specification (apparently I was wrong on that, see Daniel's answer), so you should generally avoid using it.
