Subject: Re: "- o" syntax

        I have a quick question.  What does the "-o" signify in an element
declaration?  I cite an example below from a DTD that I'm studying.

<!ELEMENT Table - o (#PCDATA|Request|%Entity1;|%Entity2;|Graphic)*>

        If I understand this correctly, #PCDATA, Request, %Entity1;, %Entity2;,
and Graphic may appear zero or more times in the "Table" element.
        Is this correct?  If so, what does the "- o" signify?  Why is it there?
