%univ-atts;

Universal attributes is a parameter entity declaration in the topic DTD, which defines a set of common attributes available on most DITA elements.

The univ-atts entity includes:

the attributes in the select-atts parameter entity
the attributes in the id-atts parameter entity
the attributes in the localization-atts parameter entity

Attributes

This section describes the attributes from select-atts, followed by those from id-atts, followed by those from localization-atts.

Name	Description	Data Type	Default Value	Required?
props	Root attribute from which new metadata attributes can be specialized. This is a property attribute which supports conditional processing for filtering or flagging. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will inherit from the closest ancestor. The attribute takes a space delimited set of values. However, when acting as a container for generalized attributes, the content model will be more complex; that model is documented in the "attribute generalization" section of the DITA architectural specification.	CDATA	#IMPLIED	No
base	A generic attribute that has no specific purpose, but is intended to act as a base for specialized attributes that have a simple value syntax like the conditional processing attributes (one or more alphanumeric values separated by whitespace). The attribute takes a space delimited set of values. However, when acting as a container for generalized attributes, the content model will be more complex; that model is documented in the "attribute generalization" section of the DITA architectural specification.	CDATA	#IMPLIED	No
platform	Indicates operating system and hardware. This is a property attribute which supports conditional processing for filtering or flagging. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will inherit from the closest ancestor. The attribute takes a space delimited set of values.	CDATA	#IMPLIED	No
product	Contains the name of the product to which the topic applies. This is a property attribute which supports conditional processing for filtering or flagging. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will inherit from the closest ancestor. The attribute takes a space delimited set of values.	CDATA	#IMPLIED	No
audience	Indicates the intended audience for the element. This is a property attribute which supports conditional processing for filtering or flagging. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will inherit from the closest ancestor. The attribute takes a space delimited set of values.	CDATA	#IMPLIED	No
otherprops	This attribute can be used for any other properties that might be needed to describe an audience, or to provide selection criteria for the element. This is a property attribute which supports conditional processing for filtering or flagging. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will inherit from the closest ancestor. The attribute takes a space delimited set of values.	CDATA	#IMPLIED	No
importance	A range of values that describe an importance or priority attributed to an element. For example, in steps of a task, the attribute indicates whether a step is optional or required.	obsolete \| deprecated \| optional \| default \| low \| normal \| high \| recommended \| required \| urgent \| -dita-use-conref-target	#IMPLIED	No
rev	Indicates revision level of an element. It is useful for flagging outputs based on revision. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will inherit from the closest ancestor.	CDATA	#IMPLIED	No
status	The status of the current element.	new \| changed \| deleted \| unchanged \| -dita-use-conref-target	#IMPLIED	No

Name	Description	Data Type	Default Value	Required?
id	An anchor point. This ID is the target for references by href and conref attributes, and for external applications that refer to DITA content.	NMTOKEN	#IMPLIED	No
conref	This attribute is used to reference an ID on content that can be reused. See The conref attribute for examples and details about the syntax.	CDATA	#IMPLIED	No

Name	Description	Data Type	Default Value	Required?
translate	Indicates whether the content of the element should be translated or not. The DITA architectural specification contains a list of each OASIS DITA element and its common processing default for the translate value.	yes \| no \| -dita-use-conref-target	#IMPLIED	No
xml:lang	Specifies the language of the element content. When no xml:lang value is supplied, the default value of English is assumed. For example, if there is a note element with the attribute xml:lang set to the value "es," then the label on the note, which normally appears as "Note" will now appear in Spanish as "Nota." The allowed xml:lang values are based on RFC 4646 Tags for Identifying Languages (see W3C: Language tags in HTML and XML).	NMTOKEN	#IMPLIED	No
dir	Specifies the directionality of text: left-to-right (ltr, the processing default) or right-to-left (rtl). See the DITA Architectural Specification for best practices related to this attribute, and other aspects of DITA and translation.	(ltr \| rtl \| lro \| rlo \| -dita-use-conref-target)	#IMPLIED	No
