object
DITA's <object> element corresponds to the HTML <object> element, and its attributes' semantics derive from their HTML definitions. For example, the type attribute differs from the type attribute on many other DITA elements.
The <object> element allows authors to include animated images, applets, plug-ins, ActiveX controls, video clips, and other multimedia objects in a topic.

Attributes
Name
Description
Data Type
Default Value
Required?
declare
When this attribute is set to declare, the current object definition is a declaration only. The object must be instantiated by a later nested object definition referring to this declaration.
declare
#IMPLIED
No
classid
Contains a URL that specifies the location of an object's implementation. It can be used together with the data attribute which is specified relative to the value of the codebase attribute.
CDATA
#IMPLIED
No
codebase
Specifies the base path (a URL) used for resolving the URL values given for classid, data, and archive attributes. If codebase is not set, the default is the base URL of the current document.
CDATA
#IMPLIED
No
data
Contains a reference to the location of an object's data. If this attribute is a URL, it is specified relative to the value of the codebase attribute. If this attribute is set, the type attribute should also be set.
CDATA
#IMPLIED
No
type
Indicates the content type for the data specified by the data attribute. This attribute should be set when the data attribute is set to avoid loading unsupported content types. Note that this differs from the type attribute on many other DITA elements.
CDATA
#IMPLIED (No default type)
No
codetype
Indicates the content type for the data specified by the classid attribute. This attribute should be set when the classid attribute is set to avoid loading unsupported content types. If this attribute value is not set, the processing default is the value of the type attribute.
CDATA
#IMPLIED
No
archive
Specifies a space-separated list of URLs indicating resources needed by the object. These resources may include those URLs specified by the classid and data attributes. Preloading these resources usually results in faster loadtimes for objects. The URLs in the list should be relative to the URL specified in the codebase attribute.
CDATA
#IMPLIED
No
standby
Contains a message to be displayed while an object is loading.
CDATA
#IMPLIED
No
height
Indicates the vertical dimension for the resulting object display. If necessary, the object is scaled to the specified size. The value of this attribute is a real number optionally followed by a unit of measure from the set of pc, pt, px, in, cm, mm, em (picas, points, pixels, inches, centimeters, millimeters, and ems respectively). The default unit is px (pixels). Possible values include: "5", "5in", and "10.5cm". If a height value is specified and no width value is specified, the width will be scaled by the same factor as the height. If both a height value and width value are specified, some implementations may not be able to scale the two directions by a different factor and may therefore ignore one of the two values.
NMTOKEN
#IMPLIED
No
width
Indicates the horizontal dimension for the resulting object display. If necessary, the object is scaled to the specified size. The value of this attribute is a real number optionally followed by a unit of measure from the set of pc, pt, px, in, cm, mm, em (picas, points, pixels, inches, centimeters, millimeters, and ems respectively). The default unit is px (pixels). Possible values include: "5", "5in", and "10.5cm". If a width value is specified and no height value is specified, the height will be scaled by the same factor as the width. If both a height value and width value are specified, some implementations may not be able to scale the two directions by a different factor and may therefore ignore one of the two values.
NMTOKEN
#IMPLIED
No
usemap
Indicates that a client-side image map is to be used. An image map specifies active geometric regions of an included object and assigns a link to each region. When a link is selected, a document may be retrieved or a program may run on the server.
CDATA
#IMPLIED
No
name
Defines a unique name for the object.
CDATA
#IMPLIED
No
tabindex
Position the object in tabbing order.
NMTOKEN
#IMPLIED
No
longdescref (deprecated)
A reference to a textual description of the graphic or object. This attribute supports creating accessible content. See The href attribute for detailed information on supported values and processing implications. For examples of how this attribute is used in output, see this this topic on long descriptions. NOTE: This attribute is deprecated in favor of the longdescref subelement to this element.
CDATA
#IMPLIED
No
univ-atts attribute group (includes select-atts, id-atts, and localization-atts groups)
A set of related attributes, described in univ-atts attribute group
global-atts attribute group (xtrf, xtrc)
A set of related attributes, described in global-atts attribute group
class, outputclass
