I didn't know about Ctrl-x 2, but I unconciously use the Emacs keystrokes. I
learnt Emacs after info, so perhaps I just don't expect info to be Emacs-like
enough?

It seems to me that the main concern is maintaining the descriptions of data
types. E.g.: if someone adds a field, then you need to update all the nodes ==
tedious and error-prone.

One solution would be to move the description into a separate file and
@include that file.

I can see a couple of problems with that solution:

(a) makeinfo would need multiple -I <directory> options, so that the data type
description files can be found.

(b) Less seriously, what to call the files? We have to name them, so that
mkdoc doesn't find them. We already use .txi and .txh. So .txd? .txp?

Problem (a) could be solved by putting all the data-type definitions in one
source directory. But that moves them away from the documentation they go
with.

Another solution to problem (a) is to get mkdoc to do the hard work. mkdoc
could generate a file containing all the -I options. Then we could invoke
makeinfo like this:

    makeinfo --no-split @makeinfo.opt libc.tex
