Namespace: I just made two important changes to the location and person tags that are breaking changes. After some discussion with Angelo at Blubrry, we decided to remove the name="" attribute from these tags and move that string to the element's node value.

So,

<podcast:person name="Dave Jones" />

...becomes:

<podcast:person>Dave Jones</podcast:person>

Same with location:

<podcast:location name="Mount St. Helens" />

...becomes:

<podcast:location>Mount St. Helens</podcast:location>
