Yes, it was quite quiet about that feature the last months... ;-)

I think, in general it's a really good idea, but for some cases,
default tags for runtime attributes would also be useful:

Example: <url> from wml::fmt::url

<define-tag url endtag=required>
{:\
    [[s|\b(http://\S+)|<a href="$1">$1</a>|g]]\
    [[s|\b(ftp://\S+)|<a href="$1">$1</a>|g]]\
    [[s|\b(gopher://\S+)|<a href="$1">$1</a>|g]]\
    [[s|\b(telnet:\S+)|<a href="$1">$1</a>|g]]\
    [[s|\b(news:\S+)|<a href="$1">$1</a>|g]]\
    [[s|\b(mailto:\S+)|<a href="$1">$1</a>|g]]\
    %body\
:}\
</define-tag>

Here it is obvious, where the runtime arguments have to go: To the <a>
tag. So here <url target=foo> should be equivalent to <url :a:target=foo>.

And there is something else, which IMHO we should think about:

Although in the above case (and probably other cases, too) with
runtime arguments, it isn't possible to distinguish to which of the
<a> tags the arguments go, e.g. a target argument doesn't make big
sense on a news or mailto link.
