Mutable elements in spec

[<Stavros.Isaiadis@uk.fujitsu.com>]

Hi all,

 

I was having a look in the Symptom specification, and I noticed that many fields in the Symptom element are declared as "mutable". Can anyone justify this? Because I cannot see why e.g. "ExpirationDate" or "Confidence" would be changed after a symptom has been emitted! To my mind, Symptom should be immutable (with the possible exception of adding a CaseRefId*), and that would potentially simplify things a lot in other aspects of the spec (e.g. interfaces and implementation guidelines).

 

Your thoughts?

 

Cheers,

 

Stavros

 

* Perhaps then this should be considered a quasi-argument against adding such CaseRefId??
