So U+2028 is Unicode "LINE SEPARATOR". What this means is that xml2rfc
now supports forced line breaks, just a few weeks (months?) after there
was a decision not to include the <br> element.

I think this is a really bad idea, as opposed to having an explicit <br>
element, because:

1. It's kind of obscure (hint: browsers do not process it as line break).

2. The grammar doesn't help people to understand where it is allowed.
Actually, where *is* it allowed? Anywhere?

So, AFAIC, if we identify cases where we want to allow forced line
breaks, we should allow them explicitly (and in the same way HTML does).

Best regards, Julian
