\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 ... -)
