It is not a question of giving credibility to this document.  We are not concerned about this document, we are concerned about the evidence you are going to give as what you think is the right answer to the questions that are put.  That is all.  This document and its validity will depend upon how it was transcribed by whom and from what source, but until then questions are put fairly to you.  You can answer those questions or if you have no recollection of the details then you may so, but to say that I am not going to answer any questions arising from this document, that is not permissible.
