Problem with SY is do you earth the braid and if you do what calculations are you going to employ to verify its capacity for carrying fault current because the chances of finding out its resistance are zero.

Braid can't carry fault current can it?
may be you should look for a firm, that will give you more experience
before you make a leap of faith by joining the niceic
Apparently the braid isn't to be used as a cpc anyway it's for screening only.
I even read an niceic article which dismisses the braid as even being an exposed conductive part as it cannot withstand fault currents.
Go figure
Well I don't believe it needs earthing but those who feel it should in case it becomes live need to calculate its capacity to carry fault current.
Definitely can't carry fault current but should always be earthed. Tin hat on and bonded.
Just don't use it and you have no problem 
Agreed. The only reason I'd use it in my house is because I always like the look of it. Good reason really. Maybe the 18th should have a section on aesthetics.
I hope @butchtaylor909 and Everyone won't mind a distraction. I'm not in the best frame tonight so it's time for the bonded tin hat joke :

Not everything that is earthed is designed to carry fault current.
