Hi Everyone,
It is possible in org-mode to do either
#+LaTeX: \somecommand
or
#+BEGIN_LaTeX
\somecommand
#+END_LaTeX
I typically use the latter (the block form) because I often have
multiple lines of LaTeX I would like to include at certain locations
of a document.
Similar to #+LaTeX, there is also #+LaTeX_HEADER, which ensures that
something is included as part of the preamble. Unfortunately,
however, there is no equivalent block form for #+LaTeX_HEADER. As a
result, when there are several items one wishes to have in the
preamble, it's necessary to have many such lines, each with a
"#+LaTeX_HEADER: " prefix.
For the sake of consistency and convenience, wouldn't it be worthwhile
to add a "LaTeX_HEADER" block type to accompany the "LaTeX" block
type?
It seems like this was proposed a couple years ago by Eric Fraga, but
didn't go anywhere because of concerns over how to decide where to
place the content of such blocks relative to the content of
"#+LaTeX_HEADER" lines. It would seem sensible to make it work
identically to how #+LaTeX lines and #+BEGIN_LaTeX blocks work -- they
are simply included in the order in which they are encountered in the
org file.
Regards,
Mark

I noticed there was also a newer thread (around a year old) on this
topic. It seems that what Nicolas Goaziou proposed earlier (about
using #+attr_latex to modify whether a latex block is a header block
or not) has not yet been implemented. This would be an alternative,
though I find it more cryptic than just having a #+begin_latex_header
block, so it would probably be more difficult for org-mode users to
find (or remember) this, and as I mentioned in my last message, it
lacks the benefit of consistency with how #+latex and #+begin_latex
relate to each other.
Nicolas' message is here:

This would not be consistent.
#+LATEX_HEADER was free for grabs but #+BEGIN_LATEX_HEADER already means
something: it is a special block. As a consequence, export back-ends
ignore LATEX_HEADER but handle BEGIN_LATEX_HEADER (basically, they
ignore the wrapper but export the contents). We would need to
make #+begin_latex_header an export block.
However, I plan to change syntax for export blocks for Org 8.4 and it
will not be possible to define arbitrarily export blocks. In fact,
#+begin_latex
...
#+end_latex
are expected to become
#+begin_export latex [attributes]
...
#+begin_export
If latex header block idea is implemented, I think it could instead use
a syntax such as
#+begin_export latex :header t
...
#+end_export
