[Css-csts] Editorial change to Framework spec

[Ray, Timothy J. (GSFC-5830)]

Dear Yves,

If, in your judgement, the recommended change is not justified, I will accept that.  However, I do want you to be aware of my rationale for suggesting the change:
If I remember correctly, in Colorado Springs we realized that if the BDD procedure didn't define a default container for data carried by a Transfer-Data-Invocation, then every service that used the BDD procedure would have to define an extension parameter.  Therefore, we changed our ASN.1 for the Transfer-Data-Invocation to add an 'OCTET STRING' as the default data container.  Later, when I saw section 4.5.2.1 again, I thought that it referred to the old (pre-Colorado Springs) ASN.1 definitions.  

Best regards,
Tim

Hi Tim,

I am not sure why would this note be valid.

The ASN.1 defines:
TransferDataInvocation              ::=   SEQUENCE
{     standardInvocationHeader      StandardInvocationHeader
,     generationTime                Time
,     sequenceCounter               IntPos
,     data                          CHOICE
      {     opaqueString            OCTET STRING
      ,     extendedData            Extended
      }
,     extensionParameter            Extended
}

The data itself is not defined here and needs to be defined by the service
using that procedure. Please let me know if I missed something.

Best regards
Yves

Hi Yves,

There is a sentence in version 0.19 of the Framework spec that I’m pretty
sure is no longer true (and should be removed):

4.5.2.1  Note – This procedure does not define the syntax of the data to be
transferred.

If 4.5.2.1 is no longer true, then section 4.5.2.1.1 should also be deleted.

Best regards,
Tim_______________________________________________
