[web2py] Creating an iTunes Compatible Podcast with Web2py

[Nite]

I am attempting to create an itunes compatible podcast using the RSS
capabilities of Web2py.

Per the Book (http://web2py.com/book/default/chapter/09#RSS) the
format is as follows:

def feed():
    return dict(title="my feed",
                link="http://feed.example.com";,
                description="my first feed",
                entries=[
                  dict(title="my feed",
                  link="http://feed.example.com";,
                  description="my first feed")
                ])

The issue is that iTunes compatible podcasts have XML files with
':' (colons) in the field name which is disallowed by python syntax
('itunes:name = foo' is disallowed).

Here's an example itunes podcast from the Apple site(http://
www.apple.com/itunes/podcasts/specs.html#example):

<itunes:name>John Doe</itunes:name>

Is there a way to use Web2py RSS capability to generate fields with a
colon in the name or do I need to write my own view and simply
populate the fields?
