I'm not sure what Dan said, I wasn't at the talk, but one think is clear,
and should be clear from readingthe note, and that is that XHTML should be
no more difficult to write than HTML

1. The elements are almost identical
2. The Attributes for the elements are also almost identical. The only
attribute that HAVE to be included are those that HAVE to be included in
HTML (e.g. alt and src attributes of the img tag)

The major differences are spelt out in the draft, but can be summarized as
follows

1. The Public identifier is different
2. There should be a namespace reference on the html element
3. ALL attributes must be given values values and the values must be quoted.
4. ALL tags and attributes must be lower case.
5. Empty elements such as <br> and <img> must take the xml form of <br/> and
<img/>. For down level interoperability it is recommended that the be a
space before the forward slash i.e. <br />
6. All elements must have a closing tag ie
<p> Some text

becomes

<p>Some text</p>

7. The <head> and <body> tags cannot be ommited.

8. The <title> element is compulsory (as it is in HTML 4.0) and it also must
be the first element in the <head> element.

As an educator I will assert that XHTML is as easy, if not easier to learn
than HTML!

The main bugaboo as far as I am concerned is the requirement for lower case.
I was an upper case guy myself, but recently I have been using lower case,
and although I won't admit to liking it I am not seriously inconvienienced.

Without giving anything away I think I can say that the WG had to make a
decision on the case issue, and it was made. As someone said "Case is
religion, there are going to be screams whatever we do!". I would reiterate
that mixed case is NOT an option in XML based languages.
