Yes. That sounds like a good idea to me. I can't think of any REALLY good reason to disallow IMG inside of a FIG. The worst that can happen is the images don't get fetched and their alternate text is used instead. For that matter, there's no technical reason why FIG should not be allowed inside of a FIG. Sure, there's no current reason why disallowing it is a problem, but future expansions of FIG functionality may make it an unreasonable restriction. Actually, I can think of a (slightly contrived) example right now where a nested FIG could be useful. Let's say you have browsers that substitute the FIG content for the image if they can't fetch the image or can't understand the image format. The author of a document might want to use an obscure image format that (s)he knows some browsers don't understand, and could use a construct like this to avoid having to write a script: <FIG src="graphic.oif"><FIG src="graphic.jpg"></FIG></FIG> A browser that didn't understand Obscure Image Format would then format the inner FIG and would be able to deal with the JPEG image. This would be a much more useful behavior than simply giving up on the outer FIG and substituting a default icon. In the future, something like this might be desirable: <FIG src="graphic.pdf"> Text that approximates the PDF contents and includes a <FIG align=right src="fig1.jpg"><CAPTION>Figure 1</CAPTION></FIG> More text that comes after the figure. </FIG> This would allow the figure to be displayed using an OLE type mechanism to format the PDF file if support is there for it, but would format the alternate content (which includes a FIG) if no PDF helper was available.
