But because browser manufacturers don't, single sourcing is a lot more
necessary. Note that you don't have to wait for browsers to support all
these features before you start using them as an authoring standard. After
all, it will be years before all pre version 5 or 6 browsers will be out of
circulation, so it will be a long time before you can rely on every client
supporting the latest standard. Use HTML 4 and CSS for authoring now and use
an Omnimark program to translate to the version of HTML your user's browser

All you need is a format that supports the storage of information you want
to keep. As you have just pointed out, CSS does this for many cases. Why go
the SGML only to convert it into the format you want with a custom developed
program when you can as easily develop a program to converts your HTML/CSS
into the format you want.
Single sourcing (at the format level) is not about finding a common
destination format, it is about finding a common source format that you can
covert into as many destination formats as you need. Sometimes content
differentiation issues will require you to move to databases and custom
markup languages, but for format differentiation, HTML/CSS will be fine for
