With the current trend towards document centered applications. There
is a great need for a simple wy to embed applets within documents. The 
XML (aka Dynamic HTML) specification allows for user defined tags within
an html document. This has a subtle but profound impact on software

to a whole complex system of applications. Currently, when a web browser
reads a document it only displays static information either textual or 
graphical. With XML a document may contain intelligent applications.
