Well, since the NIAC accepted it, I would expect they would give a name.

If I have to propose it -perhaps one day I'll join the NIAC-, I would  
go for a string attribute like:

NXintrinsic_dimension = "0D", "1D", "2D", "3D", ...

(or just NXintrinsic)

the goal of having a string attribute would be to be ready to some  
more exotic detector acquisition modes wither present ("ListMode1D",  
"ListMode2D", ...) or future.

Well, I would expect first to try something prior to decide it is not useful.

Is anybody against the (agreed) attribute being named  
NXintrinsic_dimension? Is it too long for the NeXus API?
