[O] how putting \begin{document} at the right place to export a specific latex class ?

[Joseph Vidal-Rosset]

Hello,

Here  is my  problem: for  a specific  latex class  (xxllp.cls), I  have
difficulties  to get  the \begin{document}  at the  right place  in this
add-to-list:

(add-to-list 'org-latex-classes
             '("xxllp"
               "\\documentclass\[oumk,xs]\{xxllp\}
 [NO-DEFAULT-PACKAGES]
 [NO-PACKAGES]
\\usepackage{amsmath}
\\usepackage{amssymb}
\\usepackage{blabla}
\\usepackage{blablabla}   
\\pagestyle{myheadings}\\markboth{Author}{Title of the paper}
               \\LaLPonline{??} \\setcounter{page}{1} 
\\thispagestyle{LLPrrobezissn} \\label{p}
\\AuthorTitle{Joseph Vidal-Rosset}{\\uppercase{Title of the paper}}" 
               ("\\section\{%s\} . \\section*\{%s\}")
               ("\\subsection\{%s\} . \\subsection*\{%s\}")
               ))


For this class, the \begin{document} should be just after
\\pagestyle{myheadings}\\markboth{Author}{Title of the paper}
and just before 
 \\LaLPonline{??} \\setcounter{page}{1} \\thispagestyle{LLPrrobezissn}
\\label{p}

but because I do not understand  clearly the syntax of the function, I
do not succeed and the export does not work correctly. 

Any suggestion?
