I found something that might be an error in the current xml-processing. In the following minimal example een "Undefined control sequence" error occurs for the \xmldisplayverbatim and \xmlinlineverbatims. The \xmlverbatim doesn't. \startxmldisplayverbatim ...\doinitializeverbatim \beginofverbatimlines \startbuffer[test-1] <?xml version="1.0" encoding="UTF-8"?> <myroot> <text>buffer[test-1] contents</text> </myroot> \stopbuffer \startxmlsetups load:setups \xmlsetsetup{\xmldocument}{myroot|text}{load:*} \stopxmlsetups\xmlregistersetup{load:setups} \startxmlsetups load:myroot \writestatus{TEST}{loading myroot node = #1 = \xmlname{#1}} % \xmlverbatim{#1}{text}\par \xmldisplayverbatim{#1}{text}\par % \xmlinlineverbatim{#1}{text}\par \stopxmlsetups \startxmlsetups load:text \writestatus{TEST}{node = #1 = \xmlname{#1}} \xmlflush{#1} \stopxmlsetups \enabletrackers[lxml.loading] \setuppapersize[S5][S5] \starttext \xmlprocessbuffer{myroot}{test-1}{} \stoptext Hans van der Meer
