......................................................................
Only use our hacked Node#normalize if domino is old
We used a hacky reimplementation of Node#normalize to work around
a slow array-based DOM implementation in domino; if domino is
new enough, this will break (because Node#childNodes isn't writable).
Use the built-in Node#normalize in that case instead.
