Title: DTD Notation
|
Dear Jim,
Why take the pain to work on an obselete
technology. It was not more than a year that DTD had come and everybody was
waiting for XML Schema. And this story belongs to year 1999 !
But for the question, those two lines are not
different. Parantheses are for grouping child elements into groups. The second
line ( <!ELEMENT Test2 (ItemA, ItemB?, (ItemC)*)> )
has no groups!
Yours

Subject: 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.
