I installed nxml-mode and then nxhtml-mode (and they look great, real-time validation right inside my favorite editor is just sweet).
I understand that an XHTML file is an XML file and so I can use "just" nxml-mode to edit the XHTML. But I'm a bit confused: what does nxhtml-mode offer that nxml-mode does not?
If you were to edit XHTML, would you simply use nxml-mode or would you take the time to also install nxhtml-mode?
EDIT I've of course read the first page of nxhtml, where I downloaded nxhtml.
It says this, for example:
Completion and syntax checking for XHTML
So what kind of completion, for example, does it do that nxml-mode wouldn't do?
An example of something that can be done with nxhtml and that cannot be done with nxml would be really great.
The nXhtml homepage discusses exactly this in the first section.
When I tried to use nXhtml, the reason was mumamo, which is only included in nXhtml. I needed a mult-mode solution for Rails development. It turned out that it made Emacs too laggy and didn't work perfectly all the time. I gave up after a few weeks. I never tried the completion stuff.
