I have seen previous posts commenting on these 2 questions - but I don't see a concensus on what the answers are?
QUESTION 13:
Processing instructions can be used for all of the following EXCEPT:
a) a method for passing the name of a stylesheet.
b) Use ID and IDREF attributes to represent bi-directional relationships.
c) Copy the data in a relationship into the element for the row containing the foreign key.
d) Copy the data in a relationship into the element for the row containing the primary key.
MY ANSWER:
a) and b)
QUESTION 18:
A developer needs to convert records from a relational database into XML. Each row in a table is represented as an element in the document. How can the developer represent relationships in the database?
a) Use ID and IDREF attributes to represent unidirectional relationships.
b) Use ID and IDREF attributes to represent bi-directional relationships.
c) Copy the data in a relationship into the element for the row containing the foreign key.
d) Copy the data in a relationship into the element for the row containing the primary key.
MY ANSWER:
a) and d)
Do other people agree with this?
thanks!

Kevin,
You're absolutely right about answers to #18. They're A and D.
And I have to repeat that though this doesn't make any sense, but correct answers to #13 are A and D as well. This question is a complete mess in terms how it's formed, or better to say, in terms of how irrelevnat answers are. I figured correct answers while experimenting with different combinations of answers, when I already had 43 correct out of 44. So it turned out to be A and D.
Good luck,
Svetlana.

Svetlana,
the #13 states that "Processing instructions can be used for all of the following EXCEPT:"
except is the keyword here....we can pass the name to a PI (xsl syntax) so my choice goes for b,c

Vasan,
Please justify how the option "d" can be used as PI ---
d) Copy the data in a relationship into the element for the row containing the primary key.
Thanks.

could anyone explain me how PI is related with options b, c and d in the following question. I am sure that PI is used for option a.

Well, I am still waiting for someone to clearly explain the logic behind Q 13.

The TRULY correct answer for 13) would be "a" (unless someone comes forward and justifies the validity of "d"). If they mention two of them to be correct, then mark "d" also. That's it
