For protected and public serialized fields that require a main description, an empty `@serial` block tag is appended to the doc comment instead. The effect is the same, as the main description is used in `serial-form.html` if the `@serial` tag is missing or empty. For those fields that do not have a doc comment, a doc comment with an empty `@serial` tag is added.

This is the only change in this PR that adds documentation text and causes a change in the generated documentation.
