I'd still like to see an action to handle pre-formatted text within XML. That
fits our model and seems consistent.
The other advantage is a case where some XML vocabulary uses a different tag
for what the <pre> in HTML does. Adding an action would mean that the semantic
action file could define it for any XML document.
I'm not sure about the buffer overrun. I don't think we can just globally add
<br/> at the end of lines for a couple of reasons. First of all, not all
vocabularies use <br/>. There are also times when there is a new-line char in
an XML file where there shouldn't be one. I think adding this is not really a
good idea.
Is there not a way to use a non-static buffer and just set the buffer length to
the length of the text node? Really an 8 MB buffer isn't out of the realm of
possibility on modern machines.

Well, we will have to handle programming books eventually. Of course, lines
could end in <br/> This would also solve the buffer overrun problem.
