I don't think so. The attribute argument entry dialog is terminated by a 
carriage return (Enter), so I am not aware of any way to enter a return 
(newline) in the string. If anyone does, I would like to hear it.

Yes, multi-line text can be entered in gschem. However, if the text is 
wanted to be attached to a symbol, so it moves with the symbol, then the 
"Comment" attribute is the only way I know how to do that. Again, if 
anyone has another solution, I am all ears.
