Here are my proposed validation rules for runtime-sized arrays:
v-0015: The last member of the structure type defining the "store type" for variable in the storage storage class may be a runtime-sized array.
v-0030: A runtime-sized array must not be used as the store type or contained within a store type except as allowed by v-0015
v-0031: The type of an expression must not be a runtime-sized array type.
v-0032: A runtime-sized array must have a stride attribute.
