Recursive use of namespace prefixes for better readability and file size decreasing

Restfulie creates members with namespaces prefixes like the sample below:

<feed xmlns="http://www.w3.org/2005/Atom" >
    ...
    <entry>
        ..
        <articles:body type="html" xmlns:articles="http://localhost:3000/articles">body</articles:body>
        <articles:author xmlns:articles="http://localhost:3000/articles">John Dee</articles:author>
        <articles:creation_date xmlns:articles="http://localhost:3000/articles">2010-05-03T16:29:26-03:00</articles:creation_date>
    </entry>
</feed>

Recursive use of namespace prefixes allows more concise feeds like this:

<feed xmlns="http://www.w3.org/2005/Atom" xmlns:articles="http://localhost:3000/articles">
    ...
    <entry>
        ..
        <articles:body type="html">body</articles:body>
        <articles:author>John Dee</articles:author>
        <articles:creation_date>2010-05-03T16:29:26-03:00</articles:creation_date>
    </entry>
</feed>
