Funny that Jim makes these comments today -- I was going to send out a
note tonight to make much the same point. We've had some time to mull
over HTML+ now, and to look at the progress of WWW software
development, and it is becoming apparent that HTML+ -- even after
months of revisions -- does noticeably suffer from "second system
syndrome": it just tries to do too much. I think we need to prune
some things out to make it really manageable.
If we do this, and the things we prune turn out to be very necessary
in the long term, then they will be back in HTML++. If it turns out
they're not -- i.e., if lack of tables does not turn out to actually
be a showstopper for anyone who wants to use HTML+ as a delivery
format -- then this will be apparent also and save us from having them
burden down this markup language.
If we do *not* prune some of these things, we are indeed making it
prohibitive to build browsers. It may very well be the end of next
year before Mosaic across platforms fully implements HTML+ as it
stands, and we've got a comparatively huge development effort. Is
that level of complexity the foundation we want to build WWW on in the
More and more I think the most important thing for us to do at this
point is to enable as many *applications* as possible. Fill-out forms
clearly do this, for example. Conversely, I think we have to let the
finer points of document formatting take a back seat -- the problem
domain is much bigger, and we do have to face the fact that anyone who
is going to use WWW is going to do so for its special capabilities
(distributed hypermedia, fill-out forms, etc.) and not its document
formatting capabilities (for which PostScript, PDF, TeX, etc. are
always going to be better suited, no matter how hard we work in the
context of an effort like WWW).
Like Jim, I don't want to sound negative -- I do think HTML+ is a big
step forward -- but I think we need to tackle these issues now in
order to make sure it's successful and relevant.

Agreed. I'm also ready to say let's scrap TITLE and PRINT -- I don't
think they add enough real functionality to a generic browser to
justify their existence.

Yup -- it's easy to put the "<b>NOTE:</b>" in by hand; it makes little
sense to have it in the language.

Yup -- let's standardize across all these various different methods by
specifying the same thing with what we're already doing (ISMAP --

I've never been clear on the point of those -- there doesn't seem to
be any point in time where they'd be useful. I must be missing
More comments from reading over the spec today:
intro page: Use of "light weight" seems incorrect :-).
Should standardize throughout on the term "hypermedia",
and not use "hypertext".
page 1: Should be "Uniform Resource Locator", "Uniform Resource Name".
Strike "for the nearest available copy" -- not relevant, and
not the only (or main) purpose of URNs.
"The latter being designed" should be "The latter was
Strike "It is hoped that HTML+ will be useful for information
exchange via email and network news as well as HTTP" -- there
is already no reason HTML should be considered HTTP-specific.
page 2: Kill "freely accessible" -- not relevant.
"World Web" should be "World Wide Web".
"HTML+ documents consists of" should be "HTML+ documents
page 3: This whole "HTML+ provides a means for authors to specify such
paths either explicitly via declarations at the beginning of
the node or implicitly according to the context in which a
given node is reached. Another possibility is for servers to
send such information independently, e.g. as MIME message
headers" is overkill. Why should there be two distinct
methods to accomplish the same thing? In any case, the latter
sentence should be tossed out of the HTML+ spec as irrelevant.
"You can also provide a search field that is always present
(and can't be scrolled away)" is a browser issue and not in
the scope of a markup language spec.
page 4: Strike "(preferably centered)".
Strike "flush left".
Strike "WYSIWYG editors should automatically generate
identifiers. In this case, they should provide a point and
click mechanism for defining links so that authors don't need
to deal explicitly with identifier names." Also strike
sentence after that -- shouldn't be a part of the markup spec
and in fact exposes a weakness that we don't want to deal with
yet (like I've said before: there will never be a marker where
you really need one, regardless of how many you stick in
there). Also strike following paragraph.
page 5: "you may wish to switch off word wrap with WRAP=OFF" seems to
come out of left field. In any case, do we really want that?
Isn't that what PRE/LIT is for?
Footnote: What is "H" (as opposed to "H1 to H6")?
page 6: Is " really necessary?
Where did the "Q" tag come from?
page 7: What is "<!ENTITY ...> %ISOcyr1;" stuff? Is it intended to be
in a DTD or in a HTML+ document? If the latter, we don't
normally use "%" as a prefix for anything. I suggest we just
toss it out altogether, in any case -- if we need to do
languages, let's use MIME.
page 8: Kill <U> -- underlining is too convenient, obvious, and
popular a representation method for hyperlinks; many browsers
will have to ignore it anyway.
Why superscript and subscript? If we don't do math (see
below), what applications require them? They would be quite a
bit of work to implement, and many browsers wouldn't be able
page 10: "may overwrite previous lines of text??? What???
Footnote is kinda confusing.
page 11: Omit SEETHRU paragraph.
"bigpic.giff" should be "bigpic.gif"
Clear up ambiguity introduced by saying that some servers can
Kill final paragraph in section (about "asking HTTP servers to
include images with the HTML+ document as a MIME multipart
message") -- it's far from clear that this will be implemented
in any near term.
page 12: Axe conditional text section.
Kill <L> -- it's really kinda pointless, because of <BR>.
Another mention of WRAP=OFF that doesn't seem to need to be
page 13: Kill suggestion in footnote 1.
page 18: Clarify to leave ISMAP as "?x,y" since it's already in place.
page 19: Kill second paragraph of section 8.3 altogether.
Kill tables -- they add a lot of complexity to the
requirements for a conforming browser while not provide enough
capabilities to think that they'll keep a potential
application from being show-stopped by their absence. Both
inlined images and PRE sections will be "good enough"
substitutes in most cases.
page 22: Let's use a separate METHOD attribute to keep things
Kill <htmlplus forms=off> paragraph.
Do we *really* (I mean *really*) need the MH stuff?
page 23: TYPE's default should be clarified to be a single-line text
Instances of TYPE=IMAGEMAP should be TYPE=IMAGE throughout.
Istances of MAX should be MAXLENGTH.
page 28: Kill math stuff altogether. It belongs elsewhere -- we can't
do enough of it to be competitive with existing, used systems
and so we should punt -- at least for now. Again, this is one
of those things that can reappear in HTML++ if it turns out
it's really needed -- but let's keep it out of the base
page 31: Kill htmlplus tag.
ISINDEX spec should specify encoding method beyond just
page 32: I still think NEXTID should be nuked from the spec -- let it
be used by particular editors WITHIN A COMMENT if necessary,
but it has nothing to do with the markup language.
page 47: Appendix II is way overkill. Any text-based browsers
wouldn't be able to do anything with almost all of the
symbols, and graphics-based browsers typically would need a
*lot* of complex special-case rendering code. Let's let the
normal (albeit slow) progress of system character sets solve
this problem correctly.
