Hello

I am using a filter based on the tikz example in the python pandocfilters documentation.
I am generating one id="foo" and a \label{foo} in the html and latex output, respectively, for an internal link target.

Nevertheless, when I use a link to that block, with [Look here](#foo) the link is generated to the first page, and not to the raw block that has the label defined.

I suppose that Pandoc is creating an internal index of references before generating the latex/html code (??) and is not aware that my RawBlock has a link target.

The generated LaTeX looks good to me...

A corda \emph{A} deslocada para o ponto \emph{B} regressa à base

hyperlink only links to hyperref hypertarget blocks.

So, I needed to write

\begin{figure}[h]
\centering
\hypertarget{fig1}{...}

\caption{Vibração simples}
\label{fig1}
\end{figure}

in fact, the label might be suppressed after the caption, but I decided to keep it there, as it might get handy.

Thanks and sorry for asking and answering :-)
