Please note that this isn't about favoring HTML over presentational markup
languages; none of the alternatives mentioned is a markup language at all.
RTF, TeX and text/enriched are. Consider them before choosing HTML.
It's debatable and irrelevant in this context what RTF, TeX, and
text/enriched are. The issue is whether HTML can express simple things
like bolding in quoted material - or, rather, whether such simple
expressivity is to be declared obsolete and an error (even though
browsers are required to support it).
The fact that speech renderings preserve neither bolding nor
italicization implies that implementors have not interpreted <b> and
<i> to mean bold and italics, respectively, but as hints as to
appropriate visual renderings
Speech renderings cannot present bolding and italics at all, so the
argument does not stand. It's not a matter of being hints versus
essential markup but a matter of limitations of the medium.
that happen to map quite reliably to aural renderings
No they don't, and speech renderings do not work consistently, even
though some of them may, at least with some settings on, let <b> and <i>
affect the rendering somehow. Bolding and italics are traditional
devices of print typography, with multiple uses, and many of those uses
(like italics for foreign words) do not involve any emphasis that should
be expressed in speech.
HTML was not designed for this, but could arguably be stretched to
fulfill the use case, considering existing visual implementations.
This is not about stretching anything. The B and I elements were
introduced at the same time as STRONG and EM, so they were clearly meant
to have a different meaning, namely indication of physical presentation.
The historical draft
http://www.w3.org/MarkUp/draft-ietf-iiir-html-01.txt
says this clearly, and it says:
Some of these styles are more explicit than others about how they
should be physically represented. The logical styles should be
used wherever possible, unless for example it is necessary to refer
to the formatting in the text. (Eg, "The italic parts are
mandatory".)
The preferred
solution would be a new HTML-compatible markup language (say, a
structural and presentational subset mandating a new doctype), or one
of the existing typeset file formats.
It does not sound good to tell authors to move away from HTML to a
completely different data format just because there is a need to express
bolding. And regarding new markup languages, well, they can be designed
if desired, but we would need to allow several years for delivery, and
while waiting for that, can we just keep using the well-defined
classical tags, please?
