<p>
DEPRECATED: Use the <code>ActionsGuarded</code> field instead. If RequiredToPreview is true, the question data
for the HIT will not be shown when a Worker whose Qualifications do not meet this requirement tries to preview
the HIT. That is, a Worker's Qualifications must meet all of the requirements for which RequiredToPreview is true
in order to preview the HIT. If a Worker meets all of the requirements where RequiredToPreview is true (or if
there are no such requirements), but does not meet all of the requirements for the HIT, the Worker will be
allowed to preview the HIT's question data, but will not be allowed to accept and complete the HIT. The default
is false. This should not be used in combination with the <code>ActionsGuarded</code> field.
