I have several OOXML files that generates crashes or are not rendered correctly in AOO. There was a subproject in AOO to replace the current implemtation, but the people who worked on it (IBM) got side tracked. So in short if AOO has problems with OOXML it is no surprise, and does not signal the document is wrong.
