SEQUENCE OF

For the same reason mentioned in OCTET STRINGs, SEQUENCE OFs need SIZE constraints:

        Matrix ::= SEQUENCE (SIZE(12)) OF Line

... otherwise, an error occurs:

        SequenceOf (in ...) must have a SIZE range set!

Notice that if you use base types in the SEQUENCE OF, the previously mentioned base type constraints must also exist, so this is a valid example:

        ArrayOfInt ::= SEQUENCE (SIZE(1 .. 12)) OF INTEGER (0 .. 10)

... describing an array of up to 12 integers, each one of which can contain values from 0 to 10.
