Unfortunately I choose here the otherwise because they serve no semantic
purpose. That is clutter by definition.

What I do is that when there is a new version of SDM I just print to
pages defining the error codes. I also keep manual "sdm-3d.pdf" all the
time open in Firefox.

I can understand your grief if you have a single PDF SDM but the purpose
of Linux GIT tree is not to fix your workflows :-) You can easily fix
them yourself.
