According to Table 96 — "Container requirements" the specification:
note: the destructor is applied to every element of a; any memory obtained is deallocated.
The initial "note:" can be read as if that part of the specification would not be normative (This note form differs from footnotes in tables, which have normative meaning).It seems that this initial part of the specification exists since C++98. But comparing with the similar SGI Container specification there is no evidence for that being intended to be non-normative.
NJ: If we fix this, we should also fix it elsewhere. Oh, this is the only place?
GR: If this is intended to be different from elsewhere, we should make sure.
AM: valarray specifies this without the "note:".
DK: valarray requires trivially destructible types!
GR: That's good enough for me.
NJ: First time valarray has been useful for something!
This wording is relative to N4140.
