Need to make Rich Text label as Mandatory

[divyadhanda]

Need to make Rich Text label as Mandatory in the catalog item and user uploads the file via Add an attachment , then mandatory mark should be removed. I know this can be done OOB, but i just wanted to know if there is any way to do this,

Is there any reason to not instead have an Attachment type catalog variable that is mandatory? If you are wanting to force the end user to add an attachment? You could also just have the rich text label right above this attachment catalog variable if you are wanting a special label for it?
