XML Type Editor

Overview

Complex types describe the permitted content of an element, including its element and text children and its attributes. A complex type definition consists of a set of attribute uses and a content model. The types of content model include element-only content, in which no text may appear (other than whitespace, or text enclosed by a child element); simple content, in which text is allowed but child elements are not; empty content, in which neither text nor child elements are allowed; and mixed content, which permits both elements and text to appear. A complex type can be derived from another complex type by restriction (disallowing some elements, attributes, or values that the base type permits) or by extension (allowing additional attributes and elements to appear).

Element:		A complex element is an XML element that contains other elements and/or attributes.
Element Group:		The group element is used to define a group of elements to be used in complex type definitions.
Sequence:		The sequence element specifies that the child elements must appear in a sequence. Each child element can occur from 0 to any number of times.

The Attributes tab describes an element’s attributes.
