Hi all, I'm currently experimenting with the TEI schema for critical editions. There's one thing that goes beyond my minimal understanding: for internal references, the guidelines strongly suggest defining them with the xml:id attribute. Let's take the example of a textual witness, which could be defined as <witness xml:id="A">manuscript A</witness> Whenever this witness is referenced, it will be done with a target: <rdg wit="#A">Hello</rdg> How can I catch such targets in my ConTeXt setup? Would it be possible to have the #A translated into a macro \WIT:A or something like that? Would it be possible to have ConTeXt read in the value of the <witness> tag to which the taget refers and typset that? There must be something easier than a huge set of nested \doifelse calls, but I can't quite find what would be the best way. I hope this question isn't too confusing... Thanks, and best Thomas
