[Zope3-dev] difference between view and page

[Garrett Smith]

I got my namespaces mixed up. The declaration for IHTTPPresentation is
from the zope namespace, not browser. Oops

But...I did find another example of what I'm actually confused about:

<browser:page=20
    name=3D"_traverse"=20
    for=3D"zope.interface.Interface"
    class=3D"zope.app.publication.traversers.SimpleComponentTraverser"=20
    permission=3D"zope.Public"
    />

<browser:view=20
    name=3D"_traverse"=20
    for=3D"zope.app.interfaces.content.file.IFileContent"
    class=3D"zope.app.publication.traversers.FileContentTraverser"=20
    permission=3D"zope.Public"
    />

Here, it looks like view and page (both in browser namespace) are
interchangeable.
