Specifically, what happens if I change the page URL to PHP
Markdown Extra some day?

You'll create many broken links, causing trouble for everyone
who has ever linked to your page.  Please don't do that.

Redirection can handle older links fine. The question is: will people begin to use the new URL as the profile? will tools need to be aware the two URLs are aliases? Note that this is already a problem since there is *two* URLs for that page, one with "www" in the domain and one without.

The general idea is that the name is likely to be meaningful longer than the URL. I can't guaranty the URL will hold indefinitely; bad things happen sometime. But Markdown Extra, the syntax's name, already has it's own [Wikipedia entry][1]. It's also much easier to remember "Markdown Extra" -- or "text/x-markdown.extra" -- than a URL and the syntax for writing the profile attribute in the MIME type.

If you really want a unique and permanent URI, I can probably arrange things so that something like this:

    http://michelf.com/ref/markdown-extra

can refer to the relevant documents, as long as I maintain my site. That'd be mostly the same as what the W3C does for XML namespaces: put a document at that URL that points to the related specifications.

But as I said, I don't really see the point in using a URL: it's much more cumbersome for not much added benefit.
