   Right. There can be differences between the initial value of an
attribute contained in markup and the instantaneous value in the DOM,
such as the case with <input value=""> or <option selected>, but with
<img>, I can't think of a situation where the |src| value could change
from the initial value in markup. Setting the |src| attribute's
instantaneous value and setting the value in markup are one and the same
in this case.
