Org mode version 9.5.1 (release_9.5.1-279-g8908fb @ /usr/local/share/org-mode/lisp/) GNU Emacs 28.0.50 (build 344, x86_64-pc-linux-gnu, GTK+ Version 3.24.23, cairo version 1.16.0) of 2020-12-31

Here is a use case.

I have many files each with as many as 60 tables that are generated using ob -rec. So that the tables are not evaluated during export it is convenient for me to set a buffer wide

#+PROPERTY: header-args :eval never-export.

On other hand, each file may also include, under a sub-tree latex source code blocks for signature lines, letter heads, etc.

In another sub-tree, called correspondence, those source code blocks are called using :noweb yes, such as

  #+begin_src latex :noweb yes


[Body of letter]

  #+begin_src latex :noweb yes

If I include in the correspondence sub-tree
:header-args: :eval yes

the results are a complete letter, i.e. letterhead followed by the body and then signature line.

If I do not include the ":eval yes" property in the sub-tree, only the body of the letter results, as expected.

So after all that, here are some questions:

Is ":eval yes" officially allowed and, if so, why is it not documented?

Should it be?

May its use be inferred from other examples such as those from :cache or colnames?

I found the following discussion, but it is fairly old:
