>(3) Given how popular xml2rfc is I think it makes sense to at least look at > how it would best be used to produce PDF documents containing equations and > block diagrams. I did this the N-2nd (or maybe 3rd) time we had this discussion and have refined it since. See, e.g., http://electricrain.com/fenner/tmp/draft-my-document-01.pdf . That's svg for the picture (also supported are gif, png, jpg, etc.) and latex for the equation. It's obviously just a proof of concept implementation. The editor screen when working on this document is something like http://electricrain.com/fenner/tmp/svg_eqn_editing.png . There's no WYSIWYG editing of the svn or latex, but you get to see what they look like. This is a $220 XML editor, but its job is mostly to string together other pieces of software so although it's not free software in this implementation, I don't think that means that the same thing can't be implemented with free software (e.g., it uses Batik to render the svg, and if Apache FOP improved some perhaps it could render the FOP to PDF instead of the for-pay (or free-to-download-personal-edition) RenderX) Bill _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
