I sometimes hear it said that formats like OOXML, or ODF for that matter, are simply XML serializations of a particular application's native data representation. This is said, seemingly, in an attempt to justify quirky or outright infelicitous representations. "We had no choice. Office 95 represents line widths in units of 1/5th of a barleycorn, so OOXML must as well". This technological determinism indicates poor engineering judgment, laziness, or both.
