 * `xsd2php.known_namespace_locations` (optional) Specify schema location by namespace.
   This can be used to read schemas which import namespaces but do not specify schemaLocation attributes.
 
+* `xsd2php.xml_namespaces` (optional) Specify XML namespace prefixes. If a prefix is defined for at namespace, then the
+  prefix will *always* be used in the XML element name.

 * `xsd2php.configs_jms.xml_cdata` (optional) Specify if CDATA should be used or not in serialization.
