ZUML Reference/ZUML/Namespaces

Standard Namespaces

Standard namespaces are not languages. That means they are not used to provide component definitions. Rather, they are used to provide special functionality to ZUML.

For introduction of languages vs standard namespaces, please refer to ZK Developer's References.

Namespace	Description
zk	Name: zk Namespace: http://www.zkoss.org/2005/zk Namespace shortcut: zk Java: LanguageDefinition.ZK_NAMESPACE It is the reserved namespace for specifying ZK specific elements and attributes, such as the zk element and the unless attribute. For more information please refer to the ZK Namespace section.
native	Name: native Namespace: http://www.zkoss.org/2005/zk/native Namespace shortcut: native Java: LanguageDefinition.NATIVE_NAMESPACE It is the reserved namespace for specifying native elements. A native element represents a native tag at the client. For browsers, a native element represents a HTML tag. Unlike the xhtml language, there is no component associated with, so the performance is much better but you cannot change it dynamically. For more information please refer to the Native Namespace section.
annotation	Name: annotation Namespace: http://www.zkoss.org/2005/zk/annotation Namespace shortcut: annotation Java: LanguageDefinition.ANNOTATION_NAMESPACE It is the reserved namespace for specifying annotations. For more information please refer to the annotation section.
client	Name: client Namespace: http://www.zkoss.org/2005/zk/client Namespace shortcut: client Java: LanguageDefinition.CLIENT_NAMESPACE It is the reserved namespace for specifying a ZK JavaScript widget's event listeners and attributes. For more information please refer to the Client Namespace section.
client attribute	Name: client/attribute Namespace: http://www.zkoss.org/2005/zk/client/attribute Namespace shortcut: client/attribute Java: LanguageDefinition.CLIENT_ATTRIBUTE_NAMESPACE It is the reserved namespace for specifying client-side DOM attributes. Unlike the client namespace, which assigns something to widgets, the client/attribute namespace assigns to the DOM tree directly. For more information please refer to the Client Attribute Namespace section.
xhtml	Name: xhtml Namespace: http://www.w3.org/1999/xhtml Namespace shortcut: xhtml It is the XHTML component set. For more information please refer to the the Languages section.
zul	Name: xul/html Namespace: http://www.zkoss.org/2005/zul Namespace shortcut: zul It is the ZUL component set. For more information please refer to the the Languages section.
xml	Name: xml Namespace: http://www.zkoss.org/2007/xml Namespace shortcut: xml It is the XML component set. For more information please refer to the the Languages section.
shadow	since 8.0.0 Name: shadow Namespace: http://www.zkoss.org/2015/shadow Namespace shortcut: shadow It is the reserved namespace for specifying shadow elements. For more information please refer to the Shadow Namespace.
