DTD Notation

Can someone help with a DTD notation question, please?

I'm looking at a DTD furnished by an outside source.  In the DTD, most "optional repeating" elements are defined with an asterisk, for example, <!ELEMENT Test1 (ItemA, ItemB?, ItemC*)>.  But a few are defined with additional parentheses, for example, <!ELEMENT Test2 (ItemA, ItemB?, (ItemC)*)>.

What's the difference between "ItemC*" and "(ItemC)*"?

Thanks for any insight into this (subtlety | confusion) you can give.
