How to modify the Label of a step in a Creation Wizard?

[aarasan-3]

I have a Document sub-type called "Reference_Document" sub typed from WTDocument and i'm trying to hide the attachments step in creation wizard every time a user attempts to create a Reference Document. I tried modifying the Attachment-actions.xml and included hidden=true in the action name which hides the attachment tab for all document types.

Is there a way i can do this so that attachments step only for the Reference_Document  will be hidden?

You can create a validator for this. I have a validator running to hide certain step in a wizard.

Binesh, the document seems to be pulled out from the Knowledge base, do you mind sharing a PDF here?

Also we ran into another requirement where we need to change the heading of a step in the creation wizzard for a subtyped WTDocument object type, any pointers on how to achieve this.

Thanks in advance!
