LF: Minimum content of a valid QRSS/DFCW QSO?

[Stefan Schäfer <schaefer@hst.tu-darmstadt.de>]

Dear Group, 
 
Recently i talked to Markus/DF6NM what has at least to be transmitted within a 
valid QSO in very slow DFCW. I mean a 2way contact, not a beacon reception 
report!
 
Those of you (and others) who have done successful TA QSOs may give me an 
example. Are there official rules/laws about that?
 
If i would do a QSO with Markus like that, would it be valid?:
 
Me: "dk7fc/p k"  (the /p may be cancelled but it is "my label" ;-) )
Markus: "fc df6nm O k"
Me: "nm fc r M sk"
Markus: "r sk"
 
 
73, Stefan/DK7FC
