Nicolas,

sorry for my offending remarks in the second message. i was just a little nervous about that unexpected behavior for me.

org latex classes can be considererd as a template. template is somewhat similer to lambda. you wouldnt want any function to be modified by another function which recieved it as its argument.

so if something may be inserted in the template without notice, instead it should be better if it has more arguments. say additional %s. if only there is two of them in the template you can add alternative title, this may be an option. amother option is, giving altered version explicitly. which may make it accept four templates per sectioning, numbered,unnumbered,alternative numbered, altered unnumbered. some people, at least not me, may want this feature.

if user can modify that behavior it would be definitrly better. well, that may inflate the list of vars in customs, but thats another ploblem.

the reason of cancelling the alt title, the situation im in is written in the
first message. one journal template throws an error because it does not recognize altered titles.
maybe i can write a script which regex all alt titles out, but i wanted to contribute to the development of org.

sorry for many typos, im currentry wrting on android.
