I think that it has enough description that you could take a stab at it, but if you don't want to worry about exactly how much extra spacing to use then don't implement the feature. This is not a core feature of the spec; it is a very rare bit of backwards compatibility for software that dates back two decades. I guarantee that nobody who complains about this tag possesses a document containing this feature.
If not knowing exactly how much white space to implement is going to be a major problem for you, then no standard office specification will be suitable. Look hard enough at any spec and you will find parts where they miss giving exact measurements. And if you don't do that, then the complaint will be that the specification is too verbose that it is unworkable.
And once again, it is amazing how seamlessly people can move from the argument that "there is no explanation" to "that explanation isn't good enough". It is just moving the goalposts.
