This section collects commonly used attributes, with common definitions. If an element
uses a different definition, or narrows the scope of, an otherwise common attribute,
it will be
called out in the topic that defines the element.
The universal attribute group defines a set of common attributes available on most
elements. The universal attribute group includes all attributes from the metadata,
localization, and debug attribute groups, plus the @class attribute.
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.
This attribute group collects several attributes that are used on a variety of map
elements. For a few elements, the group is modified slightly to remove an attribute
@toc or @format; in those cases the element definition will
clarify that the element does not use this full set. That is generally done in order
to specify a
default for one attribute, such as defaulting @format to "ditamap" on the
The Complex-table attribute group includes several attributes that are defined on
complex table elements. Most of these attributes are part of the OASIS Exchange model;
elements generally use only a subset of the attributes defined in this group. These
not available for the <simpletable> elements.
The link relationship attribute group includes attributes whose values can be used
representing navigational relationships. These attributes occur only on elements that
relationships among DITA elements or between DITA elements and non-DITA resources.
These common attributes are used across a wide variety of elements, with the common
definition included below. These attributes are not defined as a group, and many elements
specify one or two from this list.
The simpletable attribute group includes several attributes that are defined on the
<simpletable> element and <simpletable>
specializations. These attributes are not defined for the OASIS exchange table
