|I have some queries on HTML+ :
|first of all, is there any latest Internet RFC standard for HTML+ ?

Not yet, but the latest proposal can be found in
<ftp://15.254.100.100/pub>

|secondly, is there any formal syntax (like BNF) defined for HTML+
| Markup language?

Yes, the HTML+ DTD (`Document Type Definition') is in fact a Context
Free Grammar, though not BNF. The SGML standard describes how to
interpret the DTD and how to insert delimiters in the document.

|thirdly, what is DTD and how can one use it to build parsers? and

See above. The HTML+ DTD is a grammar for HTML+ documents. To build a
parser, you either use a general SGML parser and specialize it, or
convert the DTD to a yacc grammar. There may be parser generators that
work directly from DTDs, but I'm not sure.

|lastly, what is Pageless mode in HTMLPLUS?

I don't know. As far as I know HTML+ doesn't have the concept of page.
