re: CSS1 extension: container/noncontainer property

This does not appear to be proper SGML. I assume that an element of
such type will have a content declaration like:

<!ELEMENT BR   - O EMPTY>

Looking into the documentation, I can see the definition of the null
end tag as "/>". Is this why <BR/> is allowed? Clever!

Furthermore, where can I download the a file with the SGML
declaration, Mr. Bosak?

Thanks,
