Using the Path Query method NewLine, one can include a new line at the end of a string. Any subsequent string would be added to the new line. This article provides some examples of how NewLine can be used.
Join(NewLine)
This returns a list of objects, separated by new line.

'String' + NewLine + 'String'
This returns the two strings separated by a new line.
 
Name + NewLine + Version
Likewise, you can use it with, e.g., Name and Version
<Report>
<Text>#{? Name + NewLine + Version} </Text>
</Report>
A more complete example for a Graph can be found here.
With Variable
There is also support for this in Variable.
