Implementing ox-beamer property support in ox-latex.

[bob]

Dear list,

I recently fell in love with the properties support provided by ox-beamer. 

Especially in combination with an appropriate column view, this feature allows you to create complex presentations and maintain a good overview of all slides, layouts and possible transitions. 

Today I attempted to implement similar behaviour for ox-latex, with moderate success. 

The problem that I encountered was that you can't easily "close" environments. 

The example below shows what I mean:

* First section

** First subsection

Some text before the definition.

*** Definition 1

:PROPERTIES:

:LATEX_ENV: definition

:END:

This is a definition

*** This title is ignored and very ugly

:PROPERTIES:

:LATEX_ENV: empty

:END:

Some text behind the definition.

** Subsection

This is a new subsection.

Expands to: 

\begin{document}

\section{First section}

\subsection{First subsection}

Some text before the definition.

\begin{definition}[Definition 1]

This is a definition

\end{definition}

Some text behind the definition.

\subsection{Subsection}

This is a new subsection.

\end{document}

In order to indicate that the body of definition 1 has endend, I needed to create an empty block which is ignored by the exporter. 

Is there an elegant way to solve this problem and to "close" a heading?

Maybe in the form of an alternative carriage return character or a multiple line breaks?

Kind regards, 

Bob
