Body
Here is XSD schema: <pre><code><?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="video"> <xs:complexType> <xs:choice minOccurs="1" maxOccurs="2"> <xs:element ref="youtube"/> <xs:element ref="param" minOccurs="1" maxOccurs="unbounded"/> </xs:choice> </xs:complexType> </xs:element> <xs:element name="youtube"> <xs:complexType> <xs:attribute name="file" type="xs:string" use="required"/> </xs:complexType> </xs:element> <xs:element name="param"> <xs:complexType> <xs:attribute name="name" type="xs:string" use="required"/> <xs:attribute name="value" type="xs:string" use="required"/> </xs:complexType> </xs:element> </xs:schema> </code></pre> Example (well-formed and valid) XML: <pre><code><?xml version="1.0" encoding="UTF-8"?> <video> <youtube file="aaa"/> <param name="a1" value="b1"/> <param name="a2" value="b2"/> </video> </code></pre> There is one issue with above solution. xs:choice allows two youtube elements. There is xs:all element, which solve that, but unfortunately it's impossible to get param's maxOccurs more than one with it (xs:all limitation). In other words there is no 100% solution using XML Schema 1.0. If above is not sufficient you can use another schema language such as RELAX NG or Schematron. edit: In XML Schema 1.1 (superset of XML Schema 1.0) you can write video element as: <pre><code><xs:element name="video"> <xs:complexType> <xs:all> <xs:element ref="youtube"/> <xs:element ref="param" minOccurs="0" maxOccurs="unbounded"/> </xs:all> </xs:complexType> </xs:element> </code></pre>

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.
