Thanks Daniela, but I am afraid your answer raises more questions...

First of all - what changed in Varna? Are header units now *more* implementable or *less* implementable than described in Daniel Ruoso's paper?

Also, what does it mean, "implementable but not to the extent that e.g. Bloomberg requires"? It seems to me that something is either implementable as specified in the Standard, or it is not.
