oper

The operator (<oper>) element defines an operator within a syntax definition. Typical operators are equals (=), plus (+) or multiply (*). This element is part of the DITA programming domain, a special set of DITA elements designed to document programming tasks, concepts, and reference information.

Attributes

Name	Description	Data Type	Default Value	Required?
importance	The attribute indicates whether this item in a syntax diagram is optional, required, or default. Output processors may indicate this designation in a generated diagram. See Using the -dita-use-conref-target value for more information on the -dita-use-conref-target value.	optional \| required \| default \| -dita-use-conref-target	#IMPLIED	No
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 cascade 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; see Attribute generalization for more details.	CDATA	#IMPLIED	No
base	A generic attribute that has no specific purpose. It 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), but is not itself a filtering or flagging attribute. 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; see Attribute generalization for more details.	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 cascade 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 element 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 cascade 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 cascade 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. Alternatively, the props attribute may be specialized to provide a new metadata attribute instead of using the general otherprops attribute. 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 cascade from the closest ancestor. The attribute takes a space-delimited set of values.	CDATA	#IMPLIED	No
rev	Indicates a revision level of an element that identifies when the element was added or modified. It may be used to flag outputs when it matches a run-time parameter; it cannot be used for filtering. It is not sufficient to be used for version control.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 cascade from the closest ancestor.	CDATA	#IMPLIED	No
status	The modification status of the current element.	new \| changed \| deleted \| unchanged \| -dita-use-conref-target	#IMPLIED	No
