[DOM] missing information in the DOM specification

Step 4. 4. in node pre
insert<http://www.w3.org/TR/domcore/#concept-node-pre-insert>is

If node is a doctype <http://www.w3.org/TR/dom/#concept-doctype> and either
parent has a doctype <http://www.w3.org/TR/dom/#concept-doctype>
child<http://www.w3.org/TR/dom/#concept-tree-child>,
an element <http://www.w3.org/TR/dom/#concept-element> is
preceding<http://www.w3.org/TR/dom/#concept-tree-preceding>
 child, or child is null and parent has an
element<http://www.w3.org/TR/dom/#concept-element>
 child <http://www.w3.org/TR/dom/#concept-tree-child>.


I assume it is missing the following statement

throw a HIERARCHY_REQUEST_ERR<http://www.w3.org/TR/dom/#dom-domexception-hierarchy_request_err>
>  and terminate these steps.

If not maybe the text should be made clearer.
