A complex type describes the structure of one or more complex elements.
Complex types are an essential part of every message model, because they define the logical structure of the messages and elements in the model.
Complex types define the structure of the messages and elements in the message model. By combining elements, attributes, groups and wildcards, almost any message structure can be modeled.
Most complex types contain some elements, and some contain a large hierarchy of complex elements. The elements within a complex type are always contained within a group. This group can be local to the complex type, in which case the Message Definition Editor hides it from view. This is the usual case.
Alternatively, the group containing the elements can be a global group, and this group defines the element content, the composition and the content validation for the complex type.
If a complex type is derived from a simple type, it is not allowed to contain any element content.
The composition of a complex type describes how the members of the type are organized. For more information, see Message model objects: groups.
The Content validation parameter on a complex type specifies how strictly the contents of the type should be validated. For more information, see Message model objects: groups.
A complex type has parameters which control whether other types can be derived from it (final) and whether other types can substitute for it (block). For more information, see Substitution groups in the message model.
