Dear Silvia,

Thank you very much for your careful review of the questionnaires !!!
See some comments inlined.

If the comma is allowed in SMPTE time stamps value, then it will indeed 
prohibit to have this character as a secondary separator.

Silvia, could you please send to the list a reference where we can find 
the characters used by SMPTE?
All, what do you think?
We might want to open a new questionnaire for choosing the right 
character for the secondary separator, but you can already decide for 
the primary one ;-)

Oups, you're right, I have corrected the question.
All, please update your answers in light of this new information if you 
think it is necessary.

Again, well-spotted. Actually, I remember now that we had this 
discussion in Ghent, and in the syntax wiki page, we use single quotes 
for that reason ... I have updated the question, so all, please update 
your answers in light of this new information if you think it is necessary.

All, I can see from the preliminary results that there will be no 
consensus for all these questions, so be prepared for active discussion 
this Wednesday. The ones who disagree with the majority would need to 
argue their position ...
Best regards.
