Multiple errors and dysfunctional .tex file about asciidoctor-latex

[jfernandz]

After a few conversations in ascidoctor-mathematical repo I've realised \[\] and \(\) are not part of asciidoc syntax. That's because I've modified and extended my MWE a little bit.

== Testing

I'm also testing a few admonitions

[NOTE]
.First admonition
Here you have a note.

IMPORTANT: Here a second admonition with no title.

.Now a ordered list
. First item with a `stem` macro: stem:[\quad \rightarrow \quad a^2 - y_0] 
. Second item with a `[stem]` block
.. For the first subitem

y = Ln\left(\frac{a}{a_0}\right)

I'm trying to test stem macros and blocks in different situations. Particularly I'm getting this document body for the .tex file after give the .adoc file to asciidoctor-latex.

\admonition{NOTE}{Here you have a note.}
\begin{example}

\admonition{IMPORTANT}{Here a second admonition with no title.}
\begin{enumerate}

\item{First item with a \textttlatexmath macro: \quad \rightarrow \quad a^2 - y_0}

\item{Second item with a \texttt{[stem]} block}

\begin{enumerate}

\item{For the first subitem}

\[

\end{enumerate}

\end{enumerate}

Obviously there a malformed body as you can see, there lack a lot of math expressions originally included in the .adoc file, mainly those inside table; but also the in-line math in the first item in the ordered list.
