BBEdit works well for me. Syntax coloring and XML checking combined with a very nice side-by-side comparison-merge capability. I have no doubt there are comparable tools on Windows. But more generally, this entire discussion strikes me as a bit precious. Speaking as someone who has assumed the editorship of any number of drafts over the years, including several done in fairly obscure markup languages (bare nroff, nroff with custom macros, Andrew markup, etc.), mechanical editing issues are completely dwarfed by the difficulty of working with someone else's technical English, irrespective of how well written (or not) it is. Doing this well is not easy, especially when there are politics in play, which is almost always the case. And if all you're doing is suggesting a few changes, then just suggest them. IMO the point at which you need to work with the document source pretty much coincides with becoming an editor, with all that implies. Ned
