The second is more simple to use.
The one that should be recommended I think that it is the first because 
different kinds of constraints can be added without giving errors (at least 
when using a configuration type like Config::General).

The following code works:

<constraint>
  type Required
</constraint>
<constraint>
  type   Equal
  name repeat_password
  others password
</constraint>

But the following code doesn't work:

constraint Required
<constraint>
  type   Equal
  name repeat_password
  others password
</constraint>
And it might confuse the new users...
