X server resources that should be set.
Booleans are formatted as "true" or "false" respectively.
List elements are recursively formatted as a string and joined by commas.
All other values are directly formatted using builtins.toString.
Note, that 2-dimensional lists are not supported and specifying one will throw an exception.
If this and all other xresources options are
<code>null</code>, then this feature is disabled and no
<filename>~/.Xresources</filename> link is produced.
