NamespacesNamespaces
What Are XML Namespaces?
Provide unique names for elements and attributes
Prevent naming conflicts with other schemas
Use the xmlns attribute to declare the namespace the element belongs to
A prefix is added to the declaration to remove ambiguity

BizTalk Server
How Does BizTalk Use XML Namespaces?
Schema ATargetNamespace=“NewOrders”
Schema BTargetNamespace=“OrdersUpdate”
Message ATargetNamespace=“NewOrders”
Message ATargetNamespace=“NewOrders”
Message BTargetNamespace=“OrderUpdate”
Message BTargetNamespace=“OrderUpdate”
Message CTargetNamespace=“Inventory”
Message CTargetNamespace=“Inventory”
No Match
What Is a BizTalk XML Schema?
BizTalk uses the XML schema definition language (XSD)

Import Accesses and uses types defined in the imported schemaProvides for using types from schemas in other namespaces
Include Accesses and uses types defined in the included schemaProvides for using types from schemas in the same namespace
Redefine Accesses and uses types defined in the redefined schema Provides for using types derived from a schema in the same namespace
