docs: Faithfully assumes the provided value is "safe" and marks it not to be re-escaped. Also assumes
  the provided direction; null means unknown and thus to be estimated when necessary.
  
  <p>When you "ordain" a string as safe content, it means that Soy will NOT re-escape or validate
  the contents if printed in the relevant context. You can use this to insert known-safe HTML
  into a template via a parameter.
  
  <p>This doesn't do a lot of strict checking, but makes it easier to differentiate safe
  constants in your code.
