    What do you get if you call:
        String an = animateElem.getAttributeNS(null, "attributeName");

    I see that in your 'dump' it looks OK, but the dump can easly not
represent the details of the DOM in memory.

    Can you post the code you use to create the animate element?

   This means that in the animation bridge the getAttributeNS call
above is returning either null or "" (not entirely sure which).
Are you perhaps appending the element before setting all of it's 
attributes?
