So, basically, the <spoiler> element is already provided with the XLink
language and the show="embed" attribute.  This is esentialy the equivalent
of <a target="inline">.  See:

http://www.w3.org/TR/2001/REC-xlink-20010627/#show-att 

This is much more generic then <spoiler>, which for the most useful
applications is incorrectly named.
