Hi all. I want to use XML, but in a non-doctrinaire way: I much prefer TeX formula writing to mathml by hand. I looked at xtag-mml, and the \defineXMLenvironment [formula] looked like just what I wanted. However, when trying it, the XML catcode regime was still in effect, and the backslashes were printed, and didn't act as escapes. Am I missing something in the correct usage, or is support "incomplete"? This is a sample file, showing how I've been trying to use it: \useXMLfilter[mml] \starttext \startXMLdata <formula> t+3+x+t\neq m\alpha\frac\theta\hbar </formula> \stopXMLdata \stoptext Also, what's the status of contml? I like the idea of it as a simple, structural, basic markup that ConTeXt handles with zero effort, but is anyone actually using it? adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.
