    <p>I'm not sure if the title of my question is correct, I don't think this is be called "embedded" document, but I dont know the exact term. So, first of all: "What does this guy mean?"</p> <pre><code>&lt;somedocument&gt; &lt;item cost="34"&gt; &lt;name&gt;Apple&lt;/name&gt; &lt;description&gt;A delicious apple!&lt;/description&gt; &lt;details xmlns:apple="http://example.org/apples"&gt; &lt;apple:color&gt;red&lt;/apple:color&gt; &lt;apple:cultivar&gt;Braeburn&lt;/apple:cultivar&gt; &lt;/details&gt; &lt;/item&gt; &lt;/somedocument&gt; </code></pre> <p>Now I want to validate this document using XMLSchema. I would create a schema for all the generic details of the document like the item structure and such. I know that I can use <code>&lt;xsd:any&gt;</code> to allow any kind of other XML within another document, which I can use to allow the apple specific elements inside the <code>&lt;details&gt;</code> section. So far, so good.</p> <p>But what if I want to validate all the elements in the <code>http://example.org/apples</code> namespace? Given that the document is not limited to apples, there might be bananas, kiwis and peaches and may grow in the future to have even more "embedded" documents.</p> <p>I there something in XMLSchema I missed which can help me do that? If not, what do you do in such cases? What are alternatives you can think of? As I use the Schemas also for documentation a "just parse the document and validate all the <code>&lt;details&gt;</code>yourself in code" solution isn't ideal.</p> <p>Thank you in advance!</p> <p><em>Edit</em>: After reading my whole question again there is a big point missing:</p> <ul> <li>The <code>&lt;details&gt;</code> section is not limited to key/value pairs as seen in the example, so replacing the whole namespace and custom element stuff with a generic key/value solution does not work.</li> </ul>

    1. COI think yoou can't do that only with xml schema.It's what you say : "just parse the document and validate all the `<details>` yourself in code". Use xslt, schematron, ant, java, etc. Or explore what are those apples, bananas etc. Perhaps it's not so generic ?

    2. CODo you control the entire schema, or will third parties create sub-schemas (e.g. the schema for the `http://example.org/apples` namespace)?

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.
