I'm not sure about that one. I found myself using namespaces in STnG where I could have used context precisely because the documents are intended to be human-readable (and human-authorable) and I want the reader to see what he is dealing with. I use a sort-of-literate-programming style, where fragments of RLAXNG, XSLT and my own declarations are documented using fragments of XHTML. I want the reader to be able to know right away which part of the document he's looking at without having to scroll up or down to find the context. Ari.
