 The Serverless Workflow DSL defines several default [task](dsl-reference.md#tasks) types that runtimes **must** implement:
 
 - [Call](dsl-reference.md#call), used to call services and/or functions.
-- [Composite](dsl-reference.md#composite), used to define a minimum of two subtasks to perform.
+- [Sequential](dsl-reference.md#sequential), used to define a minimum of two subtasks to perform sequentially.
+- [Concurrent](dsl-reference.md#concurrent), used to define a minimum of two subtasks to perform concurrently.
+- [Compete](dsl-reference.md#compete), used to define a minimum of two subtasks to perform concurrently, and to continue with the first one that completes.
 - [Emit](dsl-reference.md#emit), used to emit [events](dsl-reference.md#event).
 - [For](dsl-reference.md#for), used to iterate over a collection of items, and conditionally perform a task for each of them.
 - [Listen](dsl-reference.md#listen), used to listen for an [event](dsl-reference.md#event) or more.
