Subject: :eval yes use and documentation

Message-ID: <599bf3cc-6dbe-4010-129c-a639ecd9ae70@verizon.net> (raw)
In-Reply-To: <599bf3cc-6dbe-4010-129c-a639ecd9ae70.ref@verizon.net>
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
<<SomeLetterHead>>
#+end_src
\begin{center}
\today
\end{center}
[Body of letter]
#+begin_src latex :noweb yes
<<SignatureLine>>
#+end_src
If I include in the correspondence sub-tree
:PROPERTIES:
:header-args: :eval yes
:END:
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:
