Hmm. I think the sticking block here will be the load on the validator
service at W3C. It is currently one of the highest hit points on our site,
and there probably isn't the capacity to add periodic rechecking of things.
But there is no reason why someone else doesn't offer this service, even
using the validator (it is open source and there is a download available).

It's a useful feature of authoring tools - it is probably better to have
something like asWedit, XMLSpy or HomeSite have a local validator so that as
you author you know things are staying valid, or to use something like iCab
as your browser for preview - it has a little icon that tells you whether a
page is valid or not, and a warning feature that can tell you how...

Or you could use something like Amaya, which makes it very hard work to make
anything invalid...

  A reason not to have a text-only page is the difficulty on maintaining
  separate resources.

  Looking at the page referred to in the message, I notice that it has an
  XHTML Valid icon, and is linked back to the W3C's XHTML validator (and the
  page is still valid).

  I suspect that many pages which started off valid become corrupted when they
  are updated.

  Would it be worthwhile suggesting to W3C (and other organisations such as
  CAST) that these validation services could ask for the email address of a
  page author, and periodically check that a page is still valid, and send
  email if it's not.

  There are similar services which will send email if a page contains broken

  There is a business model for providing subscriber-funded services - and
  probably not too much software development work needed to develop a free

  I author a web page that uses both HTML and a text only page using XHTML.
  Why can you not add a text only page for users who are needing to access
  informaton from your internet page?

  So he should go to all the owners of web sites whose pages are inaccessible

  What exactly are you recommending, Mr. Streett?
