[NTG-context] two easy xml-questions

Hi gang, speaking of xml... I have two easy questions, but can't find an answer. It's about tweaking the pdf-output I get: 1. How do you add an additional hyphenation to a word? How would I enter the equivalent of super\-duper in an xml-file? I tried super&addhyphen;duper with this definition: \defineXMLentity[addhyphen]{\-} in my environment, but this doesn't seem to work. 2. Similar question: how to prevent an unwanted ligature, esp. in German? In TeX, I write Kauf{}laden. What would be a good way to do this in xml? I was thinking of Kauf&nolig;laden and \defineXMLentity[nolig]{\kern0pt} Any thoughts? Thanks! Thomas
