In HTML checked is a boolean (of sorts), its presence is sufficient,
you don't need to set it to anything; if you want something unchecked
you should remove the 'checked' attribute. In XHTML, attribute
minimization is forbidden (i.e. attributes can't be empty), so the
proper syntax is checked="checked" (for disabled it's
disabled="disabled", etc.)
Use removeAttr() instead of setting the value to false.
