Well, it's of no use storing a pointer to no-stack xml::node here, is
it? That would be useful for libxml callbacks and such (which xmlwrapp
doesn't need now), but not if I want to keep a copy of xml::node
corresponding to xmlNode for its entire lifetime.

I want xml::node::begin() to return iterator that always points to the
same xml::node instance. To achieve this, I must _have_ that instance
somewhere, and it can't be on stack, obviously. So I have to either have
m_children vector in xml::node (this means dynamic allocation too) or
allocate xml::node on demand and store it with xmlNode.
