Although this is not planned to be committed, I put my comment here for future \
reference.

Unless I misunderstand something, I believe this patch is dangerous. The modification \
to KoXmlNode is not persistent at all, i.e. if you call KoXmlNode::unload() then most \
of the changes will be potentially gone. This is because the real data for the node \
is stored in KoXmlPackedDocument, which is not in sync anymore with the "edited" \
document once KoXmlNode is added, removed, shuffled, etc.

In short, KoXmlNode is mutable (for the consumer/outside world) by design.
