DTD parsing (I'm sure nxml has this, I just haven't seen it at work).

C-c C-e element insertion with TAB completion according to the DTD; the 
population of such inserted elements which have required element 
content, and the prompting for required attributes.

C-c C-r tag-region, C-c - remove-tag, and C-c = change-tag; C-c C-k 
cut-element; in fact almost all the markup-management commands, point 
movement commands, and fold/unfold.

The highlighting and indentation (I also use xxml-mode); I have no doubt 
nxml-mode can do something similar, as the highlighting is just Emacs 
fontification, and the indentation is a fairly standard requirement.

C-c C-q Rewrapping elements: psgml correctly rewraps and indents 
start-tags in element content to reveal the hierarchy (although it won't 
add newlines if you have got a start-tag following and end-tag on the 
same line *in element content*, which is a pity; and it rewraps mixed 
content to indent under the start-tag of the closest ancestor which is 
in element content (that is also influenced by xxml-mode).

C-c C-a The attribute management panel (split screen)

C-c C-w Location-ladder identity

SGML conformance (I still have half a dozen clients using SGML).

As I said, I'm sure nxml-mode provides some, if not many or even all, of 
these, but I can't yet find any comprehensive documentation, user 
conversion guide, or examples of usage. It seems to be aimed at the 
data-xml user, not the document-xml user: I actually write whole text 
documents in XML, and I must have a comprehensive set of facilities for 
doing so (refer to the table of features in my paper at Balisage in 
2006). I may simply have missed something in nxml-mode, though...
