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.
