OK, from my understanding.
If you just do a 'replace' it will do just that, it will replace the
attribute value, even if something has managed to get in before you and
changed it, so you could 'replace' the value with the same value.
If you 'delete' the old value first and it isn't the value you think it
is, the delete will fail and the entire update will fail.
if you 'add' a new value and the 'delete' failed, the 'add' will fail
because the attribute is singled valued and already exists.
