Good.  (I meant @xlink:href, not @xlink:html, as I originally wrote.)

My thinking at this point is that if the source document happens to 
include a URI (or a mangled URI) as character data, this is not worth 
checking for validity.  In character data, I can't tell apart a URI 
which for some reason isn't clickable and a fragment of a URI not meant 
to be clickable but which is included simply to illustrate a technical 
point.  But I can assume that if @xlink:href is present, the URI is 
meant to be actionable.
