Creates a controlRange collection of nontext elements.
retVal = object.createControlRange();
This method has no parameters.
There are no standards that apply here.
Creates a selection range object for control-based selection rather than text-based selection.
If a controlRange already exists, IHTMLTextContainer::createControlRange overwrites the existing element; otherwise, it returns a pointer to the element created.
If there are currently controls selected in the text container, the control range is initialized with them; otherwise, it is created empty and controls need to be explicitly added to it. This is opposite of the text range, which defaults to the whole text container if there is no selection.
