I have to tell you that I am really having a had time understanding why you 
can't see my point.

I find it burdensome, but I will try an approach that seems to have 
traction in this WG:


For "emphasis"

Webster says: 
http://www.m-w.com/cgi-bin/dictionary?sourceid=Mozilla-search&va=emphasis
[[
1 a : force or intensity of expression that gives impressiveness or 
importance to something
    b : a particular prominence given in reading or speaking to one or more 
words or syllables
2 : special consideration of or stress or insistence on something
]]

Wikipedia says: 
http://www.m-w.com/cgi-bin/dictionary?sourceid=Mozilla-search&va=emphasis
[[
-  accent the appearance, to underline, to put in bold, make something more 
significant or important.
- in typography: visual enhancement a part of a text to make it noticeable
- in discussing the Semitic languages, "emphasis" refers to certain 
phonologically differentiated stop or fricative consonant sounds. The exact 
phonological realization of emphatic consonants varies between languages
]]
See also http://en.wikipedia.org/wiki/Emphatic_consonants

Under "bold", Wikipdia says:
[[
In typography, emphasis is the exaggeration of words in a text with a font
in a different style from the rest of the text—to emphasize them.
]]

It goes on to say:
[[
The human eye is very receptive to differences in brightness within a text 
body.
One can therefore differentiate between types of emphasis according to whether
the emphasis changes the "blackness" of text.

A means of emphasis that does not have much effect on "blackness" is 
printing in italics,
where the text is written in a script style, or oblique, where the vertical 
orientation
of all letters is slanted to the left or right. With one or other of these 
techniques
(usually only one is available for any typeface), words can be highlighted 
without
making them "stick out" much from the rest of the text (inconspicuous 
stressing).
Traditionally, this is used for marking passages that have a different 
context,
such as words from foreign languages, book titles, etc.

By contrast, boldface makes text darker than the surrounding text. With 
this technique,
the emphasized text strongly stands out from the rest; it should therefore 
be used to
highlight certain keywords that are important to the subject of the text,
for easy visual scanning of text. For example, printed dictionaries often 
use boldface
for their keywords, and the names of articles can conventionally be marked 
in bold.
]]

For "italic", Wikipedia says: http://en.wikipedia.org/wiki/Italic_type
[[
Italic type is often used for emphasis to distinguish or otherwise set off 
certain words within text.
In media where italicization is not possible, alternatives are used as 
substitutes:

     * In typewritten or handwritten text, underlining is typically used.
     * In plain-text computer files, including e-mail communication,
        italicized words are often indicated by surrounding them with slashes
       or other matched delimiters. For example:
           o I was /really/ annoyed.
           o They >completely< forgot me!
           o I had _nothing_ to do with it.
           o It was *absolutely* horrible.
]]

Can we all agree, based on these references, that it is completely within 
reason to say:

- The reason that we markup text is to distinguish or emphasize it in some way.
- We often, but not always, employ visual and aural cues to signal those 
distinctions.
- There exists a rich history of typographical practice employed to signal 
distinctions.
- There exists a rich history of vocal practice employed to signal 
distinctions.
- Bold and Italic are forms of emphasis.
- It is widely understood by practitioners that systems may render bold and 
italic
    using other typographic devices if bold and italic are unavailable (or 
undesirable
    for whatever reason.

I know this stuff through 30+ years of experience. I have forgotten the 
titles of all
the books that I have written, let alone all those that I have read on the 
subjects of
typography, technical writing, publishing, and so on. It's not that I want 
to hold out
on you, it's just that I often don't remember where to look to find a 
source that
would satisfy everyone on the list.

When I am in doubt, I usually turn to Liam Quin and Michael Sperberg-McQueen
on matter related to book publishing, and to TV Raman or George Kirscher on
matters related to accessibility.

Hopefull, my exegesis above will allow you to observe that <i> and <b> are 
types of <em>.

User Agents are not required to recognize any useful semantics from <em>.
In fact, User Agents are not "required" to do much.

I just thought that you were interested in semantics and how to add 
semantics to HTML.
Maybe even today. And the point is that arguing about <b> and <i> is not 
getting
you any closer to adding semantics. It is instead clouding the issue.

If you really think that you get more semantic value out of <em> than <i>,
and you don't understand that you can use CLASS to enhance the semantic
value of any element, then the markup world is in real trouble.

Please tell me it ain't so.

I sure miss having W3C moderators to help bring the discussion back home.
Around now, I miss having the participation of Chris Lilley and Dan Connolly.

Regards,

Murray
