Custom asp:Validator that can return multiple ErrorMessages to asp:ValidationSummary

Question

Not sure if this is a silly question or not, but basically what I would like to do is have a single asp:CustomValidator for a password field which returns a list of error messages with the issue encountered during validation.

For example the password may be too short, not complex enough and contain invalid characters.

My hope is that I can set the ErrorMessage field in the validator to contain html which will allow it to render as a bulleted list with a asp:ValidationSummary control. eg ErrorMessage = <li>Password issue 1</li><li>Password issue 2</li> etc...

       {

           background-color: #FFBABA;
           border: 3px solid #bf1616;
           font-weight: bold;

       }

       .valFailure ul
       {
           padding-left: 20px;
       }

       }
   </style>
