Remove traces of <type> argument to \page command from documentation

Writing Documentation page in the qdoc Manual claims that the \page command allow a 'documentation type' as argument:

[...]

The actual documentation page of the \page command though, says

The \page command expects a single argument that represents the name of the file where QDoc should store the page.

Which one is it?
