Hi Jeremy,

its an interesting question about how extensible HTML should be
and whether it is appropriate to have non generic elements such
as <spoiler> defined in the standards. I'm not so sure that this
is a good idea as it then might be equally valid to have other non
generic tags defined in the standards as Oskar indicated.

Another way of looking at this perhaps is to ask whether XHTML 2
provides a generic mechanism by which custom elements can be defined.
I haven't absorbed all the XHTML documents but at first glance it
sounds like XHTMLMOD may be worth reading..

http://www.w3.org/TR/2001/REC-xhtml-modularization-20010410/introduction.htm
l#s_intro
	"The modularization of XHTML refers to the task of specifying
	well-defined sets of XHTML elements that can be combined and
	extended by document authors, document type architects, other
	XML standards specifications, and application and product
	designers to make it economically feasible for content developers
	to deliver content on a greater number and diversity of platforms."

Cheers

Sunil

Jeremy,

I find it tempting to add the suggested <spoiler> to XHTML 2. I agree
that its use of "show this content only when activated by the user" is
generic enough to be handled by a XHTML element. I agree that the  CSS
+scripting solution is by far not good enough. And I have to say that
@role is not a solution at all:
It might offer a way to tell what the 'spoiler' is. But it is not a way
for an author to clearly tell a browser how to act on the element marked
@role="x:spoiler", given that scripting/CSS might not work as intended
on the UA that renders the page (custom style sheets, no scripting etc).

I have to say, though, that HTML always offered the very generic "show
this content only when activated by the user"-element:
<a href="http://www.w3.org/TR/REC-html40/struct/links.html#h-12.2">Click
here only if you want to read which element it is.</a>

This is as generic as can be - and as specific as we can allow,
probably. It is not the sophisticated "show within the current
page"-solution you want. It does not fully cover all use cases:
Disturbing medical photos within a scientific text should probably be
shown right within the paragraph that describes them, not on a separate
page. But that would be <show-disturbing-medical-pictures>, not just
<spoiler> ;-)

Regards,
Oskar
