DDSXTY14 — Correct comment in Annex B struct MinimalStructMember

Annex B declares MinimalStructMemberSeq as:

// Member of an aggregate type
@extensibility(APPENDABLE) @nested
struct MinimalStructMember {
    CommonStructMember common;
    MinimalMemberDetail detail;
};
// Ordered by common.member_id
typedef sequence<MinimalStructMember> MinimalStructMemberSeq;

The comment is wrong: It contradicts section 7.3.4.5 where it says it should be ordered by member index. It is also inconsistent with struct CompleteStructMemberSeq before.

Instead, the comment before MinimalStructMemberSeq it should say:

// Ordered by the member_index

Correct comment in Annex B, struct MinimalStructMember
