13.10.10 Special blocks in LaTeX export
For other special blocks in the Org file, the LaTeX export back-end makes a special environment of the same name. The back-end also takes โ:optionsโ, if any, and appends as-is to that environmentโs opening string. For example:
#+BEGIN_abstract
  We demonstrate how to solve the Syracuse problem.
#+END_abstract
#+ATTR_LATEX: :options [Proof of important theorem]
#+BEGIN_proof
  ...
  Therefore, any even number greater than 2 is the sum of two primes.
#+END_proof
exports to
\begin{abstract}
  We demonstrate how to solve the Syracuse problem.
\end{abstract}
\begin{proof}[Proof of important theorem]
  ...
  Therefore, any even number greater than 2 is the sum of two primes.
\end{proof}
If you need to insert a specific caption command, use โ:captionโ attribute. It overrides standard โCAPTIONโ value, if any. For example:
#+ATTR_LATEX: :caption \MyCaption{HeadingA}
#+BEGIN_proof
  ...
#+END_proof
