This is not the right way to bind an attribute to a back-end player property. I
haven't looked at the other attributes to see if you're doing it that way. The
correct place to do the mapping is in the parseMappedAttribute function. The
setter should only set the attribute and the back end effect should be
triggered by parseMappedAttribute.

Otherwise, setting the attribute via setAttribute or by setting the attribute
in the initial document won't work.

Since we already know the old value here, I suggest we call the private
function only if the value is changing. That way if the private version has to
do some real work it won't get done if there's no change.

review- because of the first comment above
