Introduction to XHTML
Before we begin let's take a moment for a brief introduction to XHTML and what it is.
XHTML is a redefinition of the HTML 4.0 specification in XML. Because it is based on HTML 4, it is backward compatible with HTML 4.0 browsers. Hence, it promises to be the bridge between the Web of the past (based on HTML) and the Web of the future (based on XML).
Looking at the Differences Between XHTML and HTML
On the whole you will notice that XHTML is stricter and less forgiving than HTML. Therefore, we must be a little more careful when developing XHTML applications.
So, before we begin to develop a WebObjects application in XHTML, let's take a quick overview of the new XML and XHTML conventions we are going to have to stick to.
