+### Type Intersections
+
+Type intersections are supported, with limitations. Type intersections indicate that values, specifically object
+instances, must implement two or more interfaces simultaneously. They are written as `TypeA & TypeB`. Type intersections
+are supported with the following limitations:
+
+- All branches of the type intersection must be (behavioral) interfaces, not _structs_.
+- Type intersections may only appear in input position. That means they may only appear as a function argument,
+  or a member of a struct that is exclusively used as a function argument. That excludes them appearing as function
+  return types, class or behavioral interface members, or as struct members that are the return types of functions.
+
+Type intersection support was added in:

 ## Serialization Behavior
 
 When values are passed between the _host_ process and the `node` process, they are serialized as JSON documents. They
