This comment relates to future possibilities for FSH and relates to non-normative content. The gist of this comment relates to the suggestion in the Future section of the  possibility of using something YAML-like to deal with nested paths. So far, FSH does not treat repeated white space as meaningful. Some shorter syntax should be considered for nested paths, but it is not clear what that syntax should be. FSH certainly will not  become  YAML, which seems to be the suggestion.  We will clarify this in the "Futures" section of the Overview.
