The standard doclet is the doclet in the JDK that produces the default
HTML-formatted API output. The version that was available in previous releases
(com.sun.tools.doclets.standard.Standard) has been replaced by a new version
(jdk.javadoc.doclet.Standard).
The old version is now deprecated and is subject to removal in a future version of Java SE.
For more details, see [JEP 221](http://openjdk.java.net/jeps/221).
For more details on the new Doclet API, see the [jdk.javadoc](http://docs.oracle.com/javase/9/docs/api/jdk.javadoc-summary.html) module.
