XML Model Property Sheet Namespaces Tab

A namespace is a URI indicating a location where objects are declared. The prefix of a namespace, followed by a colon (:) and the name of an object, indicates that this object is declared in that namespace. Namespaces are not supported by DTDs.

The following tools are available on this tab:

Tool	Description
	Add Namespaces from XML Models - Adds a namespace from another XSM as a source namespace for the current model.
	Add Namespaces from XML schema files - Adds a namespace from an external schema file as a source namespace for the current model.

In the case of a model targeted with XSD, the namespace of the W3C XML Schema Recommendation is predefined in the list of namespaces.
In the case of a model targeted with XDR, two namespaces are predefined in the list of namespaces.
