Error in bash documentation for builtin declare

there is an error in the bash documentation:

In the 'declare' builtin, option '-n',  last sentence:
    "The nameref attribute cannot be applied to array variables"
is actually wrong: it can be applied to indexed and associative arrays (since bash 4.3+)

(tested for bash version : 4.3.48(1)-release (x86_64-pc-linux-gnu))

it can even be applied to functions, except that for calling, explicit dereference must be given.
