Marginalia, redux

[Jason Foster <retsofaj@mac.com>]

Long ago (in internet time anyways) some discussion of marginalia  
came up.  I've tried, and unfortunately failed, to determine the  
resolution of the discussion.

Was a formal addition made to the DocBook DTD/Schema to support side  
floats and similar elements?  If so, have the DocBook XSL stylesheets  
been updated to generate the appropriate markup?

XEP appears to support the <fo:float> tag, so generating output  
should (knock-on-wood) be possible.

Thanks!
