OperThe 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.

| 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 conref value.
| 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 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
|
| 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.
