RE: replication missing from BNF?

For concatenations and strings, look at multiple_concatenation.

However, in 1800-2009,

multiple_concatenation ::= { expression concatenation }30

whereas in V-AMS,

multiple_concatenation ::= { constant_expression concatenation }

Footnote 30 in 1800-2009 says,
"30) In a multiple_concatenation, it shall be illegal for the multiplier not to be a constant_expression unless the type of
the concatenation is string."

For array literals, you have in 1800-2009

assignment_pattern ::=
'{ expression { , expression } }
| '{ structure_pattern_key : expression { , structure_pattern_key : expression } }
| '{ array_pattern_key : expression { , array_pattern_key : expression } }
| '{ constant_expression { expression { , expression } } }

I did not see replication in V-AMS, neither in syntax nor in examples.
