Saving for CS4 with IDML

Okay, you have this InDesign CS5 file, but you need to send it to someone else…who only has InDesign CS4.…And unfortunately, you can look all you want in the Save As dialog box, but…there's no Save As CS4 feature. What will you do?…Well, the answer is not choose Save As, but choose Export.…And in the Export dialog box, choose from the Format pop-up menu, InDesign Markup.…That's IDML.…Now, you may have heard of something in InDesign called an INX file.…

But in InDesign CS5, IDML completely replaces INX.…So wherever you've ever heard of INX, just put IDML in your brain now. So what is IDML?…Well, it's a way to represent your entire file in sort of a set of XML files.…You don't need to know the technical stuff, but it's technically a bunch of XML…files that represent your file that you can then hand to an InDesign CS4 user.…They can open the IDML file and it rebuilds the document in InDesign CS4.…It's pretty clever.…Now, of course, not all the features come along for the ride.…

Any of your new InDesign CS5 features are stripped out when you open it in InDesign CS4.…
