The following declaration is for a component architecture view.

The view's type is given as IHTTPPresentation. So, it is an HTTP view.

The following declaration is for a browser page.

The the page directive implies creating browser views. That is, views of 
type zope.publisher.interfaces.browser.IBrowserPresentation.
