[NTG-context] Document Structuring

[Renaud AUBIN]

Hi all,

I have a document with the following structure:

\starttext
\startstandardmakeup
  \maketitle
\stopstandardmakeup

\setupheadertexts[][{\sl \getmarking[chapter]}]

\startfrontmatter
  \setuppagenumbering[conversion=romannumerals]
  \setuppagenumber[number=1]
  \chapter{Table des matières}
  \placecontent[alternative=c,criterium=all,interaction=all]
  \chapter{Liste des figures}
  \placelistoffigures[alternative=c,criterium=all,interaction=all]
  \component src/chapters/c_intro
\stopfrontmatter

\setupheadertexts[][{\sl \getmarking[section]}][{\sl
\getmarking[chapter]}][]

\startbodymatter
  \part{test I}
  \component src/chapters/c_simulation
  \component src/chapters/c_locomotion_robotique
  \component src/chapters/c_environnement
  \part{test II}
  \component src/chapters/c_locomotion_robot_serpent
  \component src/chapters/c_tda
  \part{test III}
  \component src/chapters/c_modelisation
  \component src/chapters/c_commande
  \part{test IV}
  \component src/chapters/c_conclusion
  %   \component src/chapters/c_chap1
  %   \component src/chapters/c_chap2
\stopbodymatter

\startappendices
  \chapter{test A}
  \chapter{test B}
\stopappendices

\setupheadertexts[][{\sl \getmarking[chapter]}]

\startbackmatter
  \chapter{Bibliographie}
  \placepublications[criterium=all,interaction=all]
\stopbackmatter
\stoptext


The normal behavior of this structure is for each "part" to reinit
pages, chapters and figures numbering.
My questions are:
1. How to change this behavior to obtain a continuous pages, chapters
... numbering ?
2. How to obtain a separated title page at the beginning of each parts
(with doublesided mngt)?
3. How to obtain (I,II,III,IV) for part numbering ?

Cheers,

Renaud
