[J3] INTENT part of Explicit Interface?

[Klemm, Michael]

Hi all,

I have another question about INTENT attributes.  Are they part of the visible interface of a subroutine or are they only visible inside the subroutine?  I'm asking this to understand if adding INTENT(IN) to a dummy argument of an existing subroutine is a breaking change or not.

Who would I find this in the standard document or other attributes?

Kind regards,
