这主要关乎假设，以及内容被放置的位置。人们认为 INT 比较可能已经“规范地”处理好了。而 BAK 和 FRT 更可能比较杂乱。这会导致您的 PDF 中出现意外的输出。
如果没有位于周边部分（periph section）之外的文本，并且所有周边部分都已正确标记为 id="something"，那么以下操作应该有效：
\StoreAllPeriphstrue
\ptxfile{A0FRTproject}
\ptxfile{99BAKproject}
\StoreAllPerphsfalse
It’s really about assumptions, and what gets put where. INT was felt to be fairly likely to have been ‘properly’ done. BAK and FRT are more likely to be messier. Which will lead to unexpected output in your PDFs.
If there is no text that’s outside a periph section, and all the periph sections have been properly flagged with id="something", then the following ought to work:
\StoreAllPeriphstrue
\ptxfile{A0FRTproject}
\ptxfile{99BAKproject}
\StoreAllPerphsfalse
