Like I said originally, "One could argue it shouldn't, and one can argue
it should."  :-)  You can easily achieve both behaviors, so all we're
talking about is default behavior.  I don't really care between the two,
although I lean toward having all the Element setAttribute() methods
have the same behavior, which is what we have now.

Classic open source.  Those doing the largest amounts of work get to
decide, since they're the lifeblood of the project.
