Remove a child of this node.
Once the pointer to the removed node disappears from the stack, the removed node will be collected in the next GC pass, but only as long as its refcount is zero. You should keep a refcount of zero for all nodes in the document except for the document node itself, because they will be held in memory by the parent.
