Security Definition Scenarios

Imported from previous forum

Hi,

I have a question regarding the
security defintion scenarios in vol 3. To me, scenario 3,4 and 5 are all examples of Security List Request, but the text refers to the Security Defintion Request & Security Defintion messages. For instance, the Security Defintion message does not have a NoRelatedSymbol field.

Is this a typeo, or have I missed something ?

thanks for any help
