If one were to pick @describedaturl, then why not, just as well, change 
@describedby to @describedBYidrefs ? I think @describedat is reasonably 
good - it fits the current naming pattern. Also, the name is probably 
not the only reason why @longdesc so often has had invalid content: 
Some lightbox libraries misuses is for 'large image URL' - probably 
because the authors were more afraid of using a new, HTML4-invalid 
attribute than they were afraid of using @longdesc for invalid purposes.
