[NTG-context] active chars in xml -- suggestions needed

Dear listmates, I need some suggestions on how to setup non breaking spaces in XML. I tried an empty element <nbsp/> to be processed as follows: \startxmlsetups xml:nbsp ~ \stopxmlsetups which was ignored by context. (I'll need something similar with \discretionary as well, I guess.) Thanks for any suggestions, Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments
