Thank you for your commentary, it is most appreciated.

Datetimes will usually be presented in a localized format to humans.

By fetching and reading a linked stylesheet. I think it's easier to 
style attributes then text nodes polluted with delimiters such as "from" 
and "by" that make reordering hard.
More importantly, how is the author to know how the user wants 
attribution presented?

A feature to one, a bug to another. The existence of the CSS height and 
width media features suggests that catering style to varying viewport 
sizes is desired by others than just me. I don't see why a user agent 
should seek an authors' permission to style a document for an unusually 
sized viewport, nor require users to write their own stylesheets instead 
of shipping customizable stylesheets.

Ops, you're correct; this should've been 1997-04-02. I'm proposing 
adding a datetime attribute to <blockquote>.

For a lack of a valid URI identifying myself, I used an unregistered 
uri-scheme ("kennitala") and my national ID as the scheme-specific part. 
The exact URI in question is unimportant to the example, but I see no 
reason to restrict values of cite to locators only, as opposed to 
identifiers in general. Quoting books identified by ISBN numbers seems 
like a good enough use case to me.

Sure I would, had I actually tried to, say, render them or validate 
before posting them on the Internet. I refrained from doing so as I knew 
this to be invalid markup, anyway. Where datetime to be a valid 
attribute of blockquote

No, that would be quite an odd rendering. More likely renderings:

It all depends on the user's localized stylesheet.

Note that a datetime in a <time> element would have to parsed just as 
date in a datetime attribute of a <blockquote>. They're both machine 
readable (and that's the best way to internationalize dates).

I've never heard this argument before. I thought we had <section> rather 
than <div role=section> because the latter has a high 
noise-to-information ratio, leading to overly verbose constructs such as:

<div role=section>
[content]
</div> <!-- end section -->

So <credit> would be an inline version of <footer>, to be contained in 
<q>? Would it not be more consistent to use attributes, in that case? 
Note that <figcaption> may contain <footer>s.

I do: use the same attributes as for <blockquote>.
Referencing people as works as I did in my examples is probably
bad (read: terrible) style. There should be a sepearate @author 
attribute for attributing an author, distinct from the @cite attribute 
for citing the work.

On a third thought, using a <footer> child of <blockquote> doesn't seem 
so confusing after all, but it'd be even less confusing to HTML 
newcomers were it named e.g. <credit>. But then it would not be an 
appropriate element for "fat footers", whatever they are. I don't see 
what citations and "fat footers" have in common.
The semantics of <footer> would be a lot clearer if "fat footers" were 
not to be enclosed in <footer>, but rather in <nav>s or <aside>s.

Were the "fat footers" example in the spec as follows, I'd have fewer 
objections.
