    <p>I need to rig up an XSD schema that will validate files partially. The file structure is:</p> <pre><code>&lt;Root&gt; &lt;Node name="core"&gt; &lt;ElementA&gt;String&lt;/ElementA&gt; &lt;ElementB&gt;String&lt;/ElementB&gt; &lt;/Node&gt; &lt;Node name="something unique"&gt; (any number of elements, with unknown names and types) &lt;/Node&gt; &lt;/Root&gt; </code></pre> <p>My XSD is something like:</p> <pre><code>&lt;xs:element name="Root"&gt; &lt;xs:complexType&gt; &lt;xs:sequence maxOccurs="unbounded"&gt; &lt;xs:element name="Node"&gt; &lt;xs:complexType&gt; &lt;xs:sequence&gt; &lt;xs:element maxOccurs="unbounded" /&gt; &lt;/xs:sequence&gt; &lt;xs:attribute name="name" type="xs:string" /&gt; &lt;/xs:complexType&gt; &lt;/xs:element&gt; &lt;/xs:sequence&gt; &lt;/xs:complexType&gt; &lt;/xs:element&gt; </code></pre> <p>Which is incomplete and not entirely correct, the un-named <code>&lt;xs:element&gt;</code> is invalid.</p> <p>There are a few nodes that are required, as well as each node having a unique name attribute; this is what I want to validate. The list of names, and the contents of those nodes, is predefined. </p> <p>The contents of nodes with unknown names is also unknown, and may contain any number of elements with any name and type, but must not have attributes or values themselves.</p> <p>The part I'm having trouble with is allowing child elements without knowing their names.</p> <p>Is it at all possible to do something like this with XSD? Is there a way to have a complex type of elements, or anyType, and an attribute?</p> <p><strong>Edit:</strong> It would be just as acceptable to use the <code>&lt;Node&gt;</code> <code>name</code>s as the element type, and then simply allow additional elements with unknown names. Either way, I need to allow nodes with unknown name and type.</p>

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.
