The thing is though, when you do a web search for ooxml, the top link (at least in Ireland) is this: " Office Open XML (OOXML) is an XML-based file format used for representing word processing documents, spreadsheets, and presentations. It is conceptually similar to ODF in many respects, though a lot of the details differ. ... https://wiki.openoffice.org/wiki/Office_Open_XML So, by that definition, docx is not ooxml
Why? Are you falling into the usual trap of confusing "Office Open XML" and "Open Office XML"? Yes, .docx is OOXML (see below for a clarification) and everything you quoted seems correct. While the page you cite comes from the OpenOffice wiki, the page describes the Microsoft Word 2007 (and later) format.
Now, this is a simplification, since OOXML is the standard (the theory) while the actual implementation (i.e., the thing that Microsoft Word writes in the .docx file) has slight deviations from the standard depending on the Microsoft Word version and settings. But, to a large degree of approximation, .docx files are OOXML files and are completely different from "OpenOffice" (i.e., ODF) files, while both formats are XML-based.
