how to interpret the XML spec?

[wenmang]

Here is what I read:
CDATA Sections
[18] CDSect ::= CDStart CData CDEnd
[19] CDStart ::= '<![CDATA['
[20] CData ::= (Char* - (Char* ']]>' Char*))
[21] CDEnd ::= ']]>'

I try to understand what "(Char* - (Char* ']]>' Char*))" means for CData ::=?
What kind of char can CData contain? thanks.

[20] CData ::= (Char* - (Char* ']]>' Char*))

This means any sequence of Chars that doesn't contain the sequence ]]>
