+## Import
+
+During preprocessing traversal, an implementation must resolve `$import`
+directives.  An `$import` directive is an object consisting of exactly one
+field `$import` specifying resource by URI string.  It is an error if there
+are additional fields in the `$import` object, such additional fields must
+be ignored.
+
+The URI string must be resolved to an absolute URI using the link
+resolution rules described previously.  Implementations must support
+loading from `file`, `http` and `https` resources.  The URI referenced by
+`$import` must be loaded and recursively preprocessed as a Salad document.
+The external imported document does not inherit the context of the
+importing document, and the default base URI for processing the imported
+document must be the URI used to retrieve the imported document.  If the
+`$import` URI includes a document fragment, the fragment must be excluded
+from the base URI used to preprocess the imported document.
+
+Once loaded and processed, the `$import` node is replaced in the document
+structure by the object or array yielded from the import operation.
+
+URIs may reference document fragments which refer to specific an object in
+the target document.  This indicates that the `$import` node must be
+replaced by only the object with the appropriate fragment identifier.
+
+It is a fatal error if an import directive refers to an external resource
+or resource fragment which does not exist or is not accessible.
+
+### Import example
+
+import.yml:
+```
+{
+  "hello": "world"
+}
+
+```
+
+parent.yml:
+```
+{
+  "form": {
+    "bar": {
+      "$import": "import.yml"
+      }
+  }
+}
+
+```
+
+This becomes:
+
+```
+{
+  "form": {
+    "bar": {
+      "hello": "world"
+    }
+  }
+}
+```
+
+## Include
+
+During preprocessing traversal, an implementation must resolve `$include`
+directives.  An `$include` directive is an object consisting of exactly one
+field `$include` specifying a URI string.  It is an error if there are
+additional fields in the `$include` object, such additional fields must be
+ignored.
+
+The URI string must be resolved to an absolute URI using the link
+resolution rules described previously.  The URI referenced by `$include` must
+be loaded as a text data.  Implementations must support loading from
+`file`, `http` and `https` resources.  Implementations may transcode the
+character encoding of the text data to match that of the parent document,
+but must not interpret or parse the text document in any other way.
+
+Once loaded, the `$include` node is replaced in the document structure by a
+string containing the text data loaded from the resource.
+
+It is a fatal error if an import directive refers to an external resource
+which does not exist or is not accessible.
+
+### Include example
+
+parent.yml:
+```
+{
+  "form": {
+    "bar": {
+      "$include": "include.txt"
+      }
+  }
+}
+
+```
+
+include.txt:
+```
+hello world
+
+```
+
+This becomes:
+
+```
+{
+  "form": {
+    "bar": "hello world"
+  }
+}
+```
