mode⚓︎ specifies the effect of this declaration on its parent object.
Status Optional
Datatype teidata.enumerated
Legal values are:
add
this declaration is part of the current definitions. [Default]
delete
the object with the same identifier (and namespace in the case of an element or attribute) as the current one is no longer part of the current definitions
change
this declaration changes the object of the same identifier (and namespace in the case of an element or attribute) in the current definition
replace
this declaration replaces the object with the same identifier (and namespace in the case of an element or attribute) in the current definition.
Note

An ODD processor should handle the values for mode as follows:

add
the object should be created (processing any children in add mode); raise an error if the object has an identifier and an object with the same identifier (and namespace in the case of an element or attribute) already exists.
replace
use this object in preference to any existing object with the same identifier (and namespace in the case of an element or attribute), and ignore any children of that object; process any new children in replace mode
delete
do not process this object or any existing object with the same identifier (and namespace in the case of an element or attribute); the element carrying this attribute must be empty: raise an error if there are any children
change
process this object and its children, replacing only those components of an existing object of the same type with the same identifier (and namespace in case of an element or attribute) that are explicitly specified. This will change only those existing attribute values and child elements that appear both in the original specification and in the new specification. Other children from the original specification will be preserved.
