title: DataMember attributes for Data validation
body: <p>I am looking to place attributes on my WCF data contract members to validate string length and possibly use regex for more granular parameter validation. </p>
  
  <p>I can the [Range] attribute for numeric and DateTime values and was wondering if any of you have found any other WCF Data Member attributes I can use for data validation. I have found a bevvy of attributes for Silverlight but not for WCF.</p>
