The attribute is not updated, it is replaced.  In the case of no namespace,
it can immediately be replaced.  Otherwise there are xml namespace rules
like you can't have two elements with a prefix foo that point to different
uri's.

You can always update an attributes value without replacing it.

Attribute att = element.getAttribute("name");
att.setValue("boo");
