The following specification needs some cleanup.
https://docs.oracle.com/javase/10/docs/specs/doc-comment-spec.html

1. The table at the end which contains valid locations for javadoc tags, this could be re-written in a nicer way, suggestion is to have a matrix and use a bullet for each application location, the locations are along the X-axis and the tags are on the Y-axis.

At the very least, duplications can be eliminated using a All declarations with Overview.

2. The serialField tag erroneously appears in overview, this should not be the case as serialField can only be used fields.
