[NTG-context] Synonyms and XML - HOWTO?

[Johannes Graumann]

Hello,

I'm trying to get the following to work:

\definesynonyms[abbreviation][abbreviations][\infull]

\defineXMLargument
  [abbrev]
  [short=,full=]
  {\expanded{\abbreviation{\XMLop{short}}{\XMLop{full}}}}

\defineXMLargument  [abbreviations]   {\completelistofabbreviations}

\starttext
  \startXMLdata
    <abbreviations/>
    Blabla short<abbrev short="short" full="slightly longer short"/>.
  \stopXMLdata
\stoptext

But I don't succeede: the synonym is not put out. Any ideas on what I'm
screwing up?

Joh
