We'll see ... It's a long way to go to turn Emacs into a rendering
XML editor. :)

Hmm. This raises a point on which I have not spent any thoughts yet
...

The one thing I find intriguing about SXML is that it maps so nicely
to a Lisp data structure. In fact, when reading about SXML I tended to
regard it primarily as a data structure, not so much as a document
format (although I realise that some people use it that way; I won't,
however).

Of course I planned to provide a function sxml-text-node-p (using
Emacs Lisp's convention to name predicate functions), but I have not
thought about hiding the /whole/ data structure behind accessor
functions. Without thinking about it I supposed that the SXML would be
processed by the usual means of list processing, with car, cdr etc.

So, when using SXML in Scheme, do people treat an SXML document as a
list of lists? Or is this considered bad style and they hide the list
structure behind accessor functions?

In the latter case it could be better for me to chose my own data
structure.
