Is it better to wrap the label tag around a form item or use the “for” attribute in HTML?

Question

I know that you can use both but is it better to use one over the other? If so, why?

Example of \"for\" attribute:

Answer 1

according to http://www.w3.org/TR/2008/WD-WCAG20-TECHS-20080430/H44.html

some assistive technologies do not correctly handle implicit labels

So when you wrap, you may also want to provide the "for" attribute to the label element.
