    <p>It's largely a matter of preference. I use Elements for grouping and attributes for data where possible as I see this as more compact than the alternative.</p> <p>For example I prefer.....</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;data&gt; &lt;people&gt; &lt;person name="Rory" surname="Becker" age="30" /&gt; &lt;person name="Travis" surname="Illig" age="32" /&gt; &lt;person name="Scott" surname="Hanselman" age="34" /&gt; &lt;/people&gt; &lt;/data&gt; </code></pre> <p>...Instead of....</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;data&gt; &lt;people&gt; &lt;person&gt; &lt;name&gt;Rory&lt;/name&gt; &lt;surname&gt;Becker&lt;/surname&gt; &lt;age&gt;30&lt;/age&gt; &lt;/person&gt; &lt;person&gt; &lt;name&gt;Travis&lt;/name&gt; &lt;surname&gt;Illig&lt;/surname&gt; &lt;age&gt;32&lt;/age&gt; &lt;/person&gt; &lt;person&gt; &lt;name&gt;Scott&lt;/name&gt; &lt;surname&gt;Hanselman&lt;/surname&gt; &lt;age&gt;34&lt;/age&gt; &lt;/person&gt; &lt;/people&gt; &lt;/data&gt; </code></pre> <p>However if I have data which does not represent easily inside of say 20-30 characters or contains many quotes or other characters that need escaping then I'd say it's time to break out the elements... possibly with CData blocks.</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;data&gt; &lt;people&gt; &lt;person name="Rory" surname="Becker" age="30" &gt; &lt;comment&gt;A programmer whose interested in all sorts of misc stuff.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
