This parameter is similar to `-header` option provided by the Standard Doclet. It specifies the header text to be placed at the top of each detail page. The header will be placed to the right of the upper navigation bar.

Additionally, when the header text is specified, it is inserted also at the top of the all package list (`overview-frame.html` file), used in the upper-left frame.

The header text may contain HTML tags and white space.

Default Value:

> The default value of this parameter will be taken from the `-header` option found on the Javadoc command line.
