Aloha all,

I am working to create a single org-mode file that exports (almost)  
identically to HTML and LaTeX.  I haven't found a way to do this for  
cross-references to figures.  I'm wondering if it would be difficult  
to change the behavior of the LaTeX exporter to recognize and  
appropriately export the argument to #+LABEL:?

This line above an org-mode table:

#+LABEL: tab:xrf

is correctly and usefully exported to LaTeX as:

\label{tab:xrf}

A link in the org-mode file like this:

  [[tab:xrf][(table 2)]]

behaves as expected in the pdf file compiled from the LaTeX export.   
In situations where it is not difficult to live without LaTeX's cross- 
referencing facility, this is great.  (I know that it is possible to  
put \ref{tab:xrf} in the org-mode file and that this works beautifully  
in the LaTeX export, but it does nothing in the HTML export.)

The #+LABEL: tab:xrf doesn't appear in HTML export from the same org- 
mode file.  If it could appear there, perhaps like this:

<a name="tab:xrf" id="tab:xrf"></a>

then one org-mode file would correctly export these cross-references  
to both LaTeX and HTML.

All the best,
Tom
