UML14 — use of stereotypes

Today, the reason for this mail is that in my UML certification I was asked a question regarding the include and extend relationship between use cases.
I was (and am still a bit) confused, because one question was dealing with the extend and include notation between use cases. I think the 640 pages UML 2 documnet 03-08-02.pdf is inconsistent here. (I now ask because I think I lost two correct answers in my fundamental UML 2 certification caused by include/includes and extend/extends...): UML 1 used the stereotype notations "extends" and "includes". Im UML 2, the classifiers are now called "include" and "extend". But confusingly enough, some association arrows inside the OMG document 03-08-02.pdf
"UML Superstructure 2.0 Draft Adopted Specification" use the stereotypes (see <<extends>> and <<includes>> in Fig 406 p. 521 and twice <<extends>> and one time <<includes>> in Table 22 on page 523/524.)

Who to report these inconsistencies to? Or are the stererotypes still allowed to be labeled <<extends>> and one time <<includes>> ?
