Hello.

Daniel Connolly referred me to you.
I have a few questions about the HTML DTD listed at
http://www.w3.org/hypertext/WWW/MarkUp/html-spec/html.dtd
I have listed my questions under each heading of the DTD. I'd appreciate it
if you could take the time to answer these questions.

thanks
sdbj

destination document to this document."
4. Does "(advisory)" indicate that the text is just for the reader of
the document's source? Do browsers typically pay attention to this?
