Hello,
I'm trying to make the following work:
1) XML:
<titlepage 
  authors="Autor Autor"
  title="Something &emdash; or <i>Something else</i>"
  subtitle="Much Fun"
  publisher="Somebody"
/>
2) ConTeXt translation rule:
\defineXMLargument[titlepage]{%
  \startstandardmakeup
    \vfil
    \bfd \setupinterlinespace Whatever \par
    \bfb \setupinterlinespace You Want \par
    \vfil
    \vfil
  \stopstandardmakeup
}
I was intending to feed the variables in through '\XMLvar', but can't get the 
start working (see 2).). I would be grateful if someone could nudge me into 
the right direction ...
Is it even possible to have XML nodes in the variables evaluated ("<i>")?
If the above isn't feasible: how would I write an import rule for something 
like:
<titlepage>
  <authors>Autor Autor</authors>
  <title>Something &emdash; or <i>Something else</i></title>
  <subtitle>Much Fun</subtitle>
  <publisher>Somebody</publisher>
</titlepage>
Thanks for any hints - need sleep now ...
\starttext

\defineXMLgrouped [i] {\em} {}

\defineXMLcommand
  [titlepage]
  {\startstandardmakeup
     \vfil
     \bfd \setupinterlinespace \XMLop{title} \par
     \bfb \setupinterlinespace \XMLop{authors} \par
     \vfil
     \vfil
   \stopstandardmakeup}

\startXMLdata
<titlepage
  authors="Autor Autor 1"
  title="Something &emdash; or Something else"
  subtitle="Much Fun"
  publisher="Somebody"
/>
\stopXMLdata

\defineXMLenvironment
  [titlepage]
  {\defineXMLsave[authors]
   \defineXMLsave[title]
   \defineXMLsave[subtitle]
   \defineXMLsave[publisher]
   \startXMLignore} % ignore undefined elements
  {\stopXMLignore
   \startstandardmakeup
     \vfil
     \bfd \setupinterlinespace \XMLflush{title}   \par
     \bfb \setupinterlinespace \XMLflush{authors} \par
     \vfil
     \vfil
   \stopstandardmakeup}

\startXMLdata
<titlepage>
  <authors>Autor Autor 2</authors>
  <title>Something &emdash; or <i>Something else</i></title>
  <subtitle>Much Fun</subtitle>
  <publisher>Somebody</publisher>
</titlepage>
\stopXMLdata

\stoptext

Here is the hint - needs to be wikified now ... -)
