Redefining the markup language on the fly?

I think the meaning of RENDER needs some clarification:

|>
[...]
|However, it will make it impossible to completely
|regularize the language as an SGML DTD. That is,
|it would be impossible to parse a document that
|added new tags in this manner.

`Render' is not used to introduce new tags, rather it is used to
define styles for elements already introduced in the document subset
(see my earlier post `Re: meta information (-->in body)' of 2 Jun
1994).

Therefore, there is no sense in using `render' without at least one of
`equiv' or `style' defined.

The HTML+ DTD shows an example (though without much explanation), see

PS. the message I referred to is archived in Nick Arnett's www-html
archive as http://198.92.133.3/www-html/12896.htm , but the layout
has suffered a bit...

PPS. There is a small error in that message, can you find it?
