We already have rel="alternate", although it's currently only defined to 
mean an alternative for the whole document, and there have been previous 
suggestions for rel="longdesc".  However, if the problem is helping 
users of assistive technology identify which links are to alternative 
content, then it still needs to be demonstrated that:

1. Something like that is actually necessary for solving the problem,
    rather than just providing suitable link text that describes its
    purpose, and
2. That it would successfully solve the problem.

I don't understand the purpose of your "slideshow" and "download" 
relationships.  People provide links to download stuff all the time 
without the need of any special link relationship.  There doesn't seem 
to be a problem with this that needs solving.

Agreed.
