Introduction
		Sometimes is is necessary to include more than just text and images in a web page.
		The recent upsurge in online music and video demonstrates this clearly. The questions
		for the web developer are:
        
          - How do we include advanced content in web pages?
- What issues are there in providing such content?
This tutorial looks at the techniques that are required and discusses 
    the range of issues to be resolved .

    The impending standardisation of HTML 5, which already has support in current 
      browsers, has made this tutorial somewhat dated. However, the principles remain, 
      and with the current state of browsers, (as of writing: IE 9beta, Opera 10.6, 
      Firefox 3.6, Safari 5 and Chrome 7, etc) support for media elements is variable 
      and adds an extra level of complexity. A separate tutorial on HTML 5 will 
      explore these issues.
