Although I would strongly prefer a standard that works directly with
existing SGML source files, I don't think that a subtly different XML will
"compete" with SGML. Hardly anyone currently serves "real SGML" on the Web
(compared to the number of people that _have_ real SGML). Most people either
don't put it on the Web, or convert it to HTML (losing a lot of
information). Either way we lose.
Although it would not be ideal, an XML that allows a simple, obvious
transform from SGML is MUCH preferable to the current situation. I see a
requirement to transform into XML as an inconvenience but not a show-stopper.

What political environment is this political suicide within? XML isn't an
ISO standard, but a W3C standard. SGML 97 will be, but it will obviously not
mention HTML at all. SGML 97 can standardize the <e/> format as the
"default" representation for "simple SGML" documents. Some HTML-based XML
documents will not be Simple SGML", just as many other legacy SGML documents
will not be Simple SGML. I don't see where political suicide comes in.
SGML 97 and XML have different legacy problems. The ERB wants some subset of
XML documents to be compatible with EXISTING BROWSERS. That seems like a
politically smart move to me.

Could a parser-implementor comment on the extra difficulty imposed by the
"don't worry, be smart" solution? How hard is it?

But we already KNOW the cost of kluges. They are _expensive_. DynaWeb is
_expensive_. DTD-specific converters are _expensive_. Panorama is expensive
because most of your users will never download it, and your information will
be lost. If these kluges were cheap, I would wait a few years for the
network to speed up, and processors to speed up and would just put raw SGML
on the Web.
"Simple SGML" (unrelated to the Web) is also interesting and important, but
it could be standardized in SGML 97.

SGML on the Web seems to be a non-starter for small to medium sized
companies/departments and individuals of all sizes. Even for big companies,
I think that it is probably misleading to call the current (or near future)
state of affairs "SGML on the Web". Panorama documents are not accessible to
the majority of Web surfers, and SGML-transformed-to-HTML isn't really SGML
anymore. If you are comfortable converting to HTML, you will be even more
comfortable converting to XML (or XHTML, in the short term).
