Understood. FWIW, here are a few examples of headings in user-defined tags in JDK: https://github.com/openjdk/jdk/blob/a6785e4d633908596ddb6de6d2eeab1c9ebdf2c3/src/java.base/share/classes/java/math/BigDecimal.java#L229-L239 https://github.com/openjdk/jdk/blob/ddbbd36e4b064b9e7433f0a55973d72cd6dbc0d3/src/java.xml/share/classes/module-info.java#L402-L420 https://github.com/openjdk/jdk/blob/6f6486e97743eadfb20b4175e1b4b2b05b59a17a/src/jdk.incubator.vector/share/classes/jdk/incubator/vector/Vector.java#L1089-L1093 ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/16388#discussion_r1449039906
