Adding a break line to a caption of single value

[Simon_Dante]

Hello everyone, 

I am trying to create a token based caption on a single value. 

The value of the caption is a string based token.

I want to add a break line in the caption or somehow change the line. 

I have tried adding /r/n, 
 and multivalue pairs but nothing seems to work. 

Any kind of help is appreciated because I am starting to think that it might not be actually possible.

Thank you.
