One of the advantages of XHTML must be that imposes some discipline in the
spaghetti code chaos of real HTML. This makes it easier to create new
applications to read it, amongst which may be assistive technologies.

Another advantage is that as it is valid XML it can be readily transformed
into other markup languages and formats using XSL transformations.

Code with errors, surely you jest!

In all seriousness, I am creating a bespoke set of checkpoints for a company
and I have at the top this: validate your code to standards. Validate again.

Is there any reason why the need for valid code is not contained within the
WCAG, especially as Jonathan has rightly pointed out that incorrect markup
will not be rendered correctly, if at all...

thanks anyway Jonathan for the answer, I had a thought that XHTML would be
better, but I thought that someone else could clarify the position for me as
I don't like getting things wrong.

Kind regards to all

my answers are never very authoritative, however i imagine that in an ideal
world xhtml will be more accessible, as xml is the future, and xhtml is a
step in the direction of xml.

My most serious concern regarding xhtml, and xml (and this future), is that
code that has errors will not be rendered, try amaya.
This is bl*** awful for anyone with dyslexia, learning difficulties, DTs,
typos or other problems, as most would I think prefer some page rather than
no page.
