"""Saving the same document twice in the same office must give the same document content: content.xml and styles.xml are
identical apart from the cached value of date and time fields. meta.xml (dates, editing duration) and the package bytes are
allowed to differ. Documents with other volatile content (NOW, TODAY or RAND formulas) are rows in data/expect/stability.tsv."""
