structure walker determines whether the ACG is well formed
(step 1532). However, if the ACG is not found to be well
formed, the user is prompted (step 1533) to edit the ACG prior
to reexecution. We therefore find that the execution is
stopped if the ACG is not well formed. By contrast, we
consider the term "paused" to mean that the rendering is
continued after the pause has ended. We find the execution of
Brotsky to be stopped, and not merely paused, because the
execution does not continue after editing is performed in
response to the edit prompt (step 1533). Upon editing an ACG
so that it is well formed, the execution process does not
continue to the next step (step 1534) where the nodes are
evaluated. Instead, the user must input another "execute ACG"
command (step 1531) and begin the "execute ACG" process from
the beginning (step 1531) and have the structure walker once
again determine if the ACG has been well formed.
We therefore find that with respect to claim 49, Brotsky
does not disclose selecting at least one field of reference
during the rendering of the representation. Nor does Brotsky
identify an image which is to be defined during the rendering
of the representation. With regard to claim 51, we find that
