When a document has been edited by more than one person, it is possible to merge the edited copies into the original. The only requirement is that the documents differ only and exclusively in the recorded changes - all other original text must be identical.
文档经过多个人的编辑后，可以将编辑过的复制件合并到原件中。唯一的要求是，文档仅在记录的修改处有所不同，而其他所有原来的文字必须完全相同。
