Complex Global Type Derivation
There are two types of inheritance in XSD: extension and restriction. BizTalk Editor provides access to this XSD functionality by using the following two Record node properties:
Base Data Type. This property provides the list of all global complex types and simple types available for use as a base data type. The complex global types can be in the same schema or in any imported schema.
Derived By. This property is used to choose between deriving by extension or by restriction. This property is automatically set to Extension when you set the Base Data Type property to any type in the list. If you set this property to (Default), any type in the Base Data Type property is removed, disabling inheritance for the node.
Note
The Content Type property is also set automatically to ComplexContent when derivation by extension or restriction is being used.
This section explains complex type derivation by using the extension and restriction mechanisms in greater detail.
