This is for writing software documentation that explains the usage of an optional property which some objects have. I'd use the two hyphens. Except non is not an english word, it is a prefix of latin origin
Lb S Top Non Nude | My XXX Hot Girl
Which is why american style manuals will always ask you to merge it with the subsequent word, without a hyphen
In case the answer is negative, is there any rule of thumb on which one may rely in order to recall whe.
Thanks for the examples as well. Leaving non stranded doesn't work either as it is a bound morpheme, a prefix not a word (in english)
