Architectural attribute group
The architectural attributes group includes a set of attributes defined for document level elements such as <topic> and <map>. These attributes are intended to provide information about the DITA namespace, what level of DITA is in use, and what vocabulary modules are in use.
- Designates the version of the architecture that is in use. The default value will increase with each release of DITA. This attribute is in the namespace "http://dita.oasis-open.org/architecture/2005/". This attribute is defined with the XML data type CDATA, but uses a default value of the current version of DITA. The current default is "1.3".
- Declares the default DITA namespace. Although this is technically a namespace rather than an attribute, it is included here because it is specified as an attribute in the DTD grammar files distributed by OASIS. The value is fixed to "http://dita.oasis-open.org/architecture/2005/".
- Indicates the specialized domains that are included in the DTD or Schema. This attribute is defined with the XML data type CDATA, and each new document type SHOULD specify a default. The value will differ depending on what domains are included in the current DTD or Schema; a sample value is "(topic ui-d) (topic hi-d) (topic pr-d) (topic sw-d) (topic ut-d) (topic indexing-d)".
