Language-specific header arguments in Org mode properties

Language-specific header arguments in Org mode properties

Language-specific header arguments are also read from properties header-args:<lang> where <lang> is the name of the language targeted. As an example

* Heading
  :PROPERTIES:
  :header-args:clojure:    :session *clojure-1*
  :header-args:R:          :session *R*
  :END:
** Subheading
  :PROPERTIES:
  :header-args:clojure:    :session *clojure-2*
  :END:

would independently set a default session header argument for R and clojure for calls and source blocks under subtree “Heading” and change to a different clojure setting for evaluations under subtree “Subheading”, while the R session is inherited from “Heading” and therefore unchanged.
