Thanks Rustle - Brain Fade on my part
probably should have said SVFR vs IFR in Class A.
The separation rules on unknown traffic do seem quite large - but I am not an airspace designer. Is it correct that an aircraft radar identified and in receipt of only FIS is 'known' and is it therefore correct that if this aircraft infringes the separation requirement is the only the 'Standard' for VFR or SVFR in class A (although logically I am not sure an infringing aircraft could be SVFR)
