OOXML is no standard, it's rather a description of how microsoft office saves documents!
Already found bugs in that "standard", ranging from copy-paste without updating identifier names in the Reference (Part4), all the way to an obvious bug in presetShapeDefinitions.xml - check out the "leftArrow" shape - uses "dy" variable without defining it in dgLst - it was meant to be "dy1"
No, it's no standard
Biting the hand that feeds IT
