+= The case Statement
+
+.Syntax
+[source,unlang]
+----
+case [ <match> ] {
+    [ statements ]
+}
+----
+
+The `case` statement is used to match data inside of a
+xref:switch.adoc[switch] statement.  The `case` statement cannot be used
+outside of a xref:switch.adoc[switch] statement.
+
+
+The `<match>` text can be an attribute reference such as `&User-Name`,
+or it can be a xref:type/string/index.adoc[string].  If the match
+text is a dynamically expanded string, then the match is performed on
+the output of the string expansion.
+
+The keyword `default` can be used to specify the default action to
+take inside of a xref:switch.adoc[switch] statement.
+
+If no `<match>` text is given, it means that the `case` statement is
+the "default" and will match all which is not matched by another
+`case` statement inside of the same xref:switch.adoc[switch].
+
+.Example
+[source,unlang]
+----
+switch &User-Name {
+    case "bob" {
+        reject
+    }
+
+    case &Filter-Id {
+        reject
+    }
+
+    default {
+        ok
+    }
+}
