What page?

Do you mean template pages, which are what is used for most larger sites
now? One can easily find existing uses of presentational attributes and
elements using command line tools with versions of grep, or using any
variety of other tools. I certainly don't believe that running a validator
such as or the W3C validator over _each and every page_ to be
an effective way to find problems at a larger site. Would you?

The days of single hand crafted web pages are over, done, a thing of the
past. It's all templates now. Templates and tools that generate the markup.
Validators aren't worth squat when it comes to ensuring templates and tools
consistently deliver the correct markup. Not unless they're somehow built
into the tools, directly.

So, yes, my approach is just as useful as taking the same page and running
it through

That's not the original context to my statement. You said that people could
find it useful to use the validator to find the presentational attributes
and elements in their web pages. I provided another approach to how people
could find these items, rather than running the page through the validator.

Now what I believe you're asking me is whether I think the strict doctypes
are unnecessary?

I never used to think so, but that was until I started mixing RDFa and
inline SVG in my web pages. About that point, I stopped using the W3C

The problems with lock-in when it comes to page vocabulary, is you never
differentiate between an accident (left the 'f' off the href, which I've
done), an error (duplicate ids, which I, or I should say my faulty template
coding, did), and a new innovation (mixing perfectly legitimate RDFa AND SVG
in XHTML, which I do).

Once you've lost the ability to differentiate between an accident, an error,
and an innovation, all you have is too much red background--all you have, is

I'm not sure, though, that this isn't drifting away from the topic of this
subthread. In a way, though, it's quite relevant to the problems with not
having a truly good means for distributed extensibility in HTML5.
