For Required Attribute condition, need to decorate the tab of the respective field or modify the error message with prefix of tab name.

Hi Guys,           
              I have case where I need to decorate the tabs, if it contains mandatory fields. 

Scenario: On saving a workitem based on 'Required Attributes For Condition' precondition,
                 the script is triggered and validates the fields and if the fields is not set,
                  an error message was displayed 'Attribute <attribute name> is not set'.

Excepted:

1. Need to mark the tab with * to which the attribute belongs. If this decoration is not possible, then
2. Need to prefix the tab name before the attribute name, eg:

                 'Attribute <attribute name> is not set' -> 'Tab <tab name> Attribute <attribute name> is not set'.

How to implment, kindly help me to me solve this,
Please provide it is whether client side scripting or java extension.

Thank you.
