• Example 90 contains lots of redundant code, which is "omitted for brevity" in the preceding examples.
• In Example 90, the @Column annotations are redundant and should be removed.
• In Example 90, the @Override annotation is used inconsistently (getName, getValue). But that's fixed by "omitting the code for brevity" above.
• The "is recommended" info box doesn't make sense since the documentation only presents a single way of defining the metadata, which follows this recommendation.
• typo: "To see how the" -> "To see the"
