I have a mild queasiness about this new overloaded use of the word "Summary", since "summary tables" are normally the summary of the contents of a declaration, like fields and methods of a class. That being said, the usage is primarily internal, and I have no overwhelmingly wonderful alternative, and (overloading aside) the term is accurate. So, OK for now. We can change it later if we want to. src/jdk.javadoc/share/classes/jdk/javadoc/internal/doclets/toolkit/util/Utils.java line 2949: > 2947: > 2948: /** > 2949: * Return the set of preview language features used to declare the > given element.
