Table Of Contents
A client might encounter a VCloudExtension element in any response. If the element declares
required=”true” and the client does not know how to interpret the contents of the element, the client can
ignore it, but it must include the VCloudExtension in any request to modify the element that contains it. A
server must return a failure when a request includes a VCloudExtension element that declares
required=”true” but the server does not understand the extension. For more information about
VCloudExtension, see the schema reference.

XML Namespace Identifiers
Elements used as request or response bodies contain a set of attributes that enable XML validation. The
body of a PUT or POST request must contain all XML namespace identifiers required to validate the
elements it contains. A response body typically includes all the XML namespace identifiers that the server
used to validate it, in addition to other attributes that specify the schema locations searched during
validation.
The vCloud API uses these XML namespace identifier attributes and prefixes.

XML Namespace Prefixes in Request and Response Bodies
When a request or response includes elements from multiple XML namespaces, each element name is
prefixed with a namespace identifier. Unless all elements in a request or response originate in the same XML
namespace, these prefixes are required in request bodies, and are always included in response bodies.
