Re: [rfc-i] line wrapping in XML

[Mark Nottingham <[e-mail]>]

The problem is that this happens in blocks like this:

<t>This document introduces a set of common data structures for use in definitions of new HTTP field values to address these problems. In particular, it defines a generic, abstract model for them, along with a concrete serialization for expressing that model in HTTP <xref target="RFC7230" format="default"/> header and trailer fields.</t>

which becomes:

<t>This document introduces a set of common data structures for use in
definitions of new HTTP field values to address these problems. In
particular, it defines a generic, abstract model for them, along with a
concrete serialization for expressing that model in HTTP 
<xref target="RFC7230" format="default" />header and trailer fields.</t>

Notice the removed space after the <xref> element. I don't think xml:space="preserve" is the solution here.

This has been reported to Tidy many times over the years:
