Please can someone explain the following error and why the one specific XML input fails? It turns out that a single node <node/> is not accepted by the core whereas others are ok. This is the error message in the log, first line from my debug statement: HVDM-VOC > load vocabulary from buffer "german" xml > core > load error in [buffer: german]: invalid xml file - parsed text Minimal code to explain what is done: % Loading from buffer. \def\loadvocabularyfrombuffer#1{% \writestatus{HVDM-VOC}{load vocabulary from buffer "#1"}% \XMLProcessBuffer{#1}% % simply does an \xmlprocessbuffer{}{}{} } The following buffer gives the error: \startbuffer[german] <vocabulary use="de"/> \stopbuffer \loadvocabularyfrombuffer{german} But the others below are ok and load as expected. \startbuffer[german] <vocabulary use="de"></vocabulary> \stopbuffer and \startbuffer[german] <root><vocabulary use="de"/></root> \stopbuffer dr.
