+     * RemoveIterator removes an item from a sequence at a certain position,
+     * while retaining the pull-based characteristic of being an QAbstractXmlForwardIterator itself. The
+     * RemovalIterator's constructor is passed an QAbstractXmlForwardIterator, the QAbstractXmlForwardIterator to
+     * remove from, and the position of the item to remove. When calling the RemovalIterator's
+     * functions, it acts as an ordinary QAbstractXmlForwardIterator, taking into account that
+     * one item is removed from the source QAbstractXmlForwardIterator.
+     *
+     * The RemovalIterator class contains the central business logic for implementing the
+     * <tt>fn:remove()</tt> function, whose definition therefore specifies the detailed behaviors
+     * of RemovalIterator.
