To ensure that specific coding does not cause any import problems with
different releases, this coding has been turned into comments. (Unless
it has been designed in such a way that it is <zh>not</>
release-dependent.) During "Initial Load of Objects", the system
temporarily turns the coding into comments, and does a syntax check. If
this syntax check fails, the coding is kept as a comment.
