Data sharing attributes

[m_van_waveren]

Here is a question related to data sharing attributes in OpenMP 3.0

The bottom of 2.9.1.1 (Page 80) says :
Additional restrictions on the variables whose data-sharing
attributes cannot be implicitly determined in a task construct are
described in the Restrictions section of the firstprivate clause
(Section 2.9.3.4 on page 92).

Does this statement mean a variable implicitly determined
"firstprivate" in a task clause need to be restricted as firstprivate ?
In case the variable cannot be "firstprivate" because of the
restriction, is the program error ?

The answer to both questions is yes.
