dtd notation

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

None.

the () is a sequence or choice  so you could have for example
(ItemC|ItemD)*   : one or more of C or D
(ItemC,ItemD)*   : one or more copies of the sequence C  D
but if there's only one thing in the () then they are not doing
anything (in particular they are not doing any harm:-)
