You missed out a more relevant part of section B.1 :

* If a user agent encounters an attribute it does not recognize, it
should ignore the entire attribute specification (i.e., the
attribute and its value).

They don't want browsers to be upset by unrecognised attributes. On the
other hand, they aren't asking for them to appear in the browser's DOM.

XHTML isn't that extensible. You would need to use namespaces, and even
that is not part of strict XHTML 1.0.
