Re: [rfc-i] line wrapping in XML

[Martin Thomson <[e-mail]>]

I just tested tidy and it's almost good enough, but it has one major problem that I've found.

FWIW, this is what I ran:
tidy -xml -o tls.xml -w 80 -i draft-ietf-quic-tls.xml

The problem is that there are places in the document like this:

> This document describes how QUIC <xref target="QUIC-TRANSPORT" format="default" /> is

And tidy removes the space after the <xref/>, which is quite unfortunate.
