+### `namespace`
+
+A Table Dialect descriptor `MAY` have the `namespace` property that `MUST` be a string; undefined by default. This property specifies a database schema (namespace).
+
+For example, the database with the tables below:
+
+```txt
+raw.table
+cleaned.table
+```
+
+With this dialect definition:
+
+```json
+{
+  "table": "table",
+  "namespace": "cleaned"
+}
+```
+
+`SHOULD` output the data from the second table.
+
 ## Excluded
 
 Table Dialect has nothing to do with the names, contents or types of the headers or data within the CSV file (see [Table Schema](/standard/table-schema/) instead), only how it is formatted. However, Table Dialect does allow the presence or absence of a header to be specified, similarly to [RFC4180](http://www.ietf.org/rfc/rfc4180.txt).
