title: Is there any documentation for Microsoft asp.net and mvc front-end scripts
body: <p>I use the Mvc2 and its native validation system.
  Some js files are included by default, for example:
  MicrosoftAjax.js
  MicrosoftMvcAjax.js
  MicrosoftMvcValidtion.js</p>
  
  <p>I need to make some more complex validation procedures, which means I need to understand these scripts.
  Is there any documentation about these scripts? 
  I searched thoroughly but find nothing... Microsoft doesn't document?</p>
