+CUSTOM USER ATTRIBUTES FORMAT
+===========================
+
+Custom attribute format style may be changed in project settings with 
+CAS_CUSTOM_ATTRIBUTES_FORMAT constant. You can provide your own formatter callback
+or specify existing in this package in `attribute_formatters` module.
+
+Attribute formatter callback takes two arguments:
+
+*  `auth_success` - `cas:authenticationSuccess` node. It is `lxml.etree.SubElement`instance;
+*  `attrs` - dictionary with user attributes received from callback specified in 
+    CAS_CUSTOM_ATTRIBUTES_CALLBACK in project settings. 
+
+Example of generated XML below:
+ 
+     <cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>
+         <cas:authenticationSuccess>
+             <cas:user>jsmith</cas:user>
+
+             <!-- extended user attributes wiil be here -->
+
+             <cas:proxyGrantingTicket>PGTIOU-84678-8a9d2sfa23casd</cas:proxyGrantingTicket>
+         </cas:authenticationSuccess>
+     </cas:serviceResponse>
+
+
+* Name-Value style (provided in `cas_provider.attribute_formatters.name_value`):
+
+    <cas:attribute name='attraStyle' value='Name-Value' />
+    <cas:attribute name='surname' value='Smith' />
