Validation is one point.

But clear semantics is not less important.

A high-level node, inserted in a tree to give it a more orderly structure,
is neither a low-level container for unspecified stuff, nor a note,
nor a log, nor a parameter container.

Perhaps the name change and it's non-implementation at SNS are a fortunate
coincidence we could use to codify their current use of "NXgroup"?
