I think you can modify them in place. The components earlier in the
pipeline should already be done with this object and the ones after the
normalizer would want to be consuming the normalized XMLAttributes. There's
a special implementation of XMLAttributes in the org.apache.xerces.dom.
DOMNormalizer (called XMLAttributesProxy) which may not currently be
excepting that, though I'm sure it could be updated so that it's fully
read-write if it's necessary.
