For completeness, I'll mention here what has been discussed ad nauseum on 
XML-DEV.

The most effective way out of this limbo is a specification for an 
instance-level ID attrbibute type declaration, such as the

<?xml-id-attr "foo bar"?>

or

xml:id-attr="foo bar"

proposals that have been made by Tim Bray, John Cowan, James Clark, and others.
