If you put a gun to my head, I’d pick “most widely used” over “standardized”. HTML 5 happens to be a standard (or two), and yet
The more familiar I become with the W3C standard, the more I tend agree with this statement.
Didn’t you get the memo? 
Apparently, my command of English is insufficient for me to grasp this contraption. Doesn’t itemized mean consisting of items, or simply a list?
I couldn’t imagine anyone having an issue with the term “ordered list”. Until now. 
In CM the different unordered list markers determine whether an item belongs to an existing list (i.e.
- foo
+ bar
result in two distinct lists), whereas in ordered lists the first marker determines the start index.
As for presentation, the following is a perfectly standard HTML ordered list (the Arabic numerals are only provided for illustration):
甲、1
乙、2
丙、3
丁、4
戊、5
己、6
庚、7
辛、8
壬、9
癸、10
