Thanks, Richard, for your detailed reply...I have implemented it and so far it
seems to be working (LyX 2.03 on Ubuntu 11.10)...However, step (ii) above
(renaming IEEEtran.layout) seems to cause problems, because, apparently LyX
assumes there would a matching class called IEEEtran-bytype.cls...I reverted
the
name back to IEEEtran.layout and that seems to have fixed it... (I suppose I
could have also made a copy of the class named IEEEtran-bytype.cls and it might
have worked).
Anyway, I just choose article(IEEEtran) as before...Even after multiple
reconfigure/restart cycles, the new layout does not show if I click on "Local
Layout" on the left sidebar (between Modules and Fonts), but I can find it by
clicking on the button labelled "Local Layout" to the right of the Document
Class drop-down choice, and browsing...have no idea of the difference between
the button and the side-bar menu both labelled "Local Layout", but one of the 2
works.
The solution does have some obvious disadvantages...notably, one would need
different "tweaked" layouts to be able to use different Theorem numbering
conventions in different docs (which may very well be needed/wanted since, as
discussed in the OP, there is no IEEE-wide convention on this matter, so
different publication outlets could impose different conventions; likewise,
different collaborators may have different preferences on this matter...
anyway, the workaround suffices for the time being.
It is rather unfortunate that it has not been possible to fix whatever it is
that prevents a Theorem module choice through standard LyX means, without
modifying the layout...if I understand correctly, the whole point of this
functionality is precisely to enable such choices on a per-document basis,
conveniently through the LyX menus...As you indicated, the limitation has been
known for about 2 years...perhaps some maintainers do believe that the "by
type"
convention is not allowed by the IEEE (which, as discussed in the OP, is not
the case) and hence fixing it is not worth the trouble.
I find puzzling that somehow once the layout is tweaked as discussed above,
everything seems to work both within LyX and at the LaTeX level, yet one cannot
make the choice within LyX in the "normal" LyX way...it seems that whatever it
is only affects the ability to choose the module through the LyX UI.
Anyhow, it would be great if it became possible for this problem to be fixed in
the next minor release.
Thanks again.
Virgil
