It is a distinction without a difference. HTML is a formal language and
it can viewed as a programming language for a certain (very important
and very powerful) form of graphic user interface.

This is the basis of its use in client-server systems on intranets and
it is a major contribution to the technology of such systems. Document-oriented
interfaces overcome the rigidity of classical GUI's and are supporting
the development of new types of system.

However, none of this indicates that the "programming language" has to be
extended to encompass every aspect of a multimedia interface. There is
a spectrum of possibilities between HTML level 2 and C++, and the debates
over particular extensions are about what features might be generically
useful and what might be best left to specialist extensions.

Javascript and Java plugins address computational extensions and Shockwave
etc addresses multimedia extensions.

The strength of HTML as a GUI programming language is that it supports such
extensibility, and hence supports modern component-based software design.

It is remarkable that this has been possible while retaining the original
facilities to present high-quality documents. What has been achieved is
a digital extension of print document technology to become something that
subsumes it and is very much more powerful.
