oMath and Math Arguments

The oMath element ("[ECMA-376] Part 4 §; oMathPara") and the math argument elements deg ("[ECMA-376] Part 4 §; deg"), den ("[ECMA-376] Part 4 §; den"), e ("[ECMA-376] Part 4 §; e"), fName ("[ECMA-376] Part 4 §; fName"), lim ("[ECMA-376] Part 4 §; lim"), num ("[ECMA-376] Part 4 §; num"), sub ("[ECMA-376] Part 4 §; sub"), and sup ("[ECMA-376] Part 4 §; sup") can each contain an unbounded number of elements from the following list:

XML elements in any namespace not defined by Word 2003 XML (which can, in turn, hold any valid child element of the oMath element ("[ECMA-376] Part 4 §; oMath"))

The AML annotation element

The Word 2003 XML hlink element

The Word 2003 XML permEnd element

The Word 2003 XML permStart element

When included as a child of a math argument element, those elements must occur after any Office Open XML Math argPr element ("[ECMA-376] Part 4 §; argPr") and before any Office Open XML Math ctrlPr element ("[ECMA-376] Part 4 §; ctrlPr") which is also a child of that math argument element.
