  WWW can inherently use several protocols to fetch data. Some of them
may be limited to 7-bit characters, but the WWW architecture itself is
designed with full 8-bit bytes. In particular, the HTTP protocol that
we have defined supports 8-bit data. However, HTML, our language for
describing hypertext, is based on SGML which is essentially a 7-bit
construct (actually, it can only handle a predefined set of characters).

  Your impression may come from the fact that in the current
implementation, as HTTP can only return HTML documents, the
distinction between them is not clear. The new phase of HTTP that we
are currently designing will be able to handle documents of arbitrary
types. These documents are then processed by the client program
depending on its own capabilities, with the possible help of external
converters or applications, much like the Xwais.filters stuff.
