IBM comments on WCAG 2.0, 2004 Public Draft

To whom it may concern,
            My name is Roman Ali and I am a second-year undergraduate
computer science student at the University of Manchester.  I am a
technology enthusiast, and therefore happened to be browsing your
website for no particular reason other than to learn a bit more about
Web development.  Anyway, recently I had clicked on one of your =93valid
XHTML=94 links (found at the bottom of most of your Web pages) and found
that some of these pages did not actually validate.  This seemed
somewhat ironic, and amusing, for a person such as myself, considering
the fact that the World Wide Web Consortium is considered to be the
world authority of Web development.  I let you know of this via email.
Today I clicked on one of these pages again and was pleased to see
that
it did validate.  However, the results page (which says the referring
page has validated) also had a link to validate it (i.e. to validate
the
result=92s page).  The result=92s page arising from that also had a link
in
the same fashion.  This trend continued for all the results pages I
received.  It occurred to me that this could negatively affect your
systems IF you have not anticipated this in advance, and have not
pre-emptively put in measures to deal with such a situation.  You
probably have put in any necessary measures to deal with such a
situation, but I felt obliged to express my opinions just in case you
hadn=92t.  I am sure you have understood what I have said, but in case I
have not been clear enough, I shall give an example below.

If I click on the =93valid XHTML 1.0=94 link at the bottom of the page
located at: HYPERLINK
I receive the following results page: HYPERLINK
http
://validator.w3.org/check?uri=3Dhttp%3A%2F%2Fvalidator.w3.org%2F
If I then click on the =93valid XHTML 1.0=94 link at the bottom of the
results page I have just received, I receive another results page:
If I then click on the =93valid XHTML 1.0=94 link at the bottom of this
new
results page I have just received, I receive another results page:
HYPERLINK
=20
In my opinion, if some malicious person, or someone who isn=92t
malicious
but ignorant, keeps continuing to click on the =93valid XHTML 1.0=94 links
found on the results pages of validations he/she has carried out in an
iterative manner, the long addresses generated by such validations
could
possibly negatively affect your systems and/or their browser.  This is
not a professional opinion as I am a student at the moment with
limited
knowledge.  I would appreciate it very much if you would kindly let me
know whether the opinion I have expressed is true or not.  I ask for
this just so that I may increase my knowledge even further.  Thank
you.
Yours faithfully
            Roman Ali.
