The Properties tab displays information about a component you select in the Navigator. If the component is a complex element, you can view element properties in the schema, such as namespace, type, and content. When you view a simple element or attribute, the Properties tab shows the type and length of the element. The Properties tab also displays annotations.

If you import the definition from an XML file, you can edit the datatype and cardinality from the Properties tab. If you create the definition from a DTD file, you can edit the component type.

If a schema uses a namespace, you can change the namespace, prefix, and schema location for the namespace. The prefix identifies the elements or attributes that belong to a namespace. Elements and attributes in a default namespace have no prefix. You can select a namespace as a default namespace for an XML target.
