[O] Confusion about attr_latex and new exporter

Just making the transition to the new exporter, finally, today. Just
some notes regarding the documentation that I wanted to pass along. I
think there's some possibly conflicting information (or at least
ambiguous) out there.

- From the Worg page on transitioning to the new exporter

Attribute lines now take plists:
#+attr_latex :width "5cm"
#+attr_beamer :options "width=5cm"


However, from a previous email, I think a caveat should be added, as I
found the above misleading in trying my first test drive of the new
exporter. I recalled an earlier response on the mailing list to an
inquiry I had about the old exporter, which evolved into some
discussion about the new one:
- http://lists.gnu.org/archive/html/emacs-orgmode/2013-02/msg00850.html

So, as this pertains to the transitioning guide: using =:width= as an
example of the new syntax is perhaps a bad idea since it's heavily
associated with #+attr_latex: width=Xcm for images and yet is
incorrect for image attributes. At the very least, some further
specification of the :width option should probably be referenced right
then and there.

Another fantastic quote one might consider adding, which really helped
make things "click" for me is from the same thread a bit later:
- http://lists.gnu.org/archive/html/emacs-orgmode/2013-02/msg00882.html

#+begin_quote Nicolas

An argument within curly brackets gets its own keyword. Optional arguments
are stuffed within an `:options' keyword.


That's quite helpful!
- \begin{tabular}{align=blah} --> :align "blah" (curly gets :keyword)
- \includegraphics[width=blah]{file.jpg} --> :options "width=blah"
(optional gets :options)

Now, even having digested some of this a bit better, using any syntax
option (at least that I can tell is correct from the above) with
quotes yields quotes in the resulting .tex file and a resultant fail
of pdflatex compilation.

In other words:

- Org:
attr_latex: :options "width=5cm"

- LaTeX:

- Org
attr_latex: :align "lp{4cm}"
| column 1 | column 2 |

- LaTeX:

I also tried =:width "5cm"= for images. Despite this being options and
sounding like it needs to be in the :options string instead of :width,
it still works but quoted parts still get quotes =[width="5cm"]= in
the resultant .tex file. If I remove quotes, it works. That's fine,
but not sure if I'll ever run into any multi-word option occurrences
where I'll possibly need quotes to differentiate one set of option
values from another (don't think I've run into this before, but just
thinking out loud).

Am I doing something wrong if this is the behavior I'm getting, or is
the documentation incorrect and I shouldn't be quoting these options?
