-An [`AbstractModelAttribute`](@ref) for the `Vector{ConstraintIndex}` of all
-constraints that participate in the conflict with index `conflict_index`.
-
-The `conflict_index` is 1 by default, but it can be set to any value between
-1 and the number of conflicts found by the solver, as indicated by
-[`ConflictCount`](@ref).
-
-## Implementation
-Optimizers may implement the following methods:
-```julia
-MOI.get(
-    ::Optimizer,
-    ::MOI.ListOfConstraintIndicesInConflict,
-)::Vector{MOI.ConstraintIndex}
-```
-A ineficient fallback is available for `get`.
-They should not implement [`set`](@ref) or [`supports`](@ref).
