What is the use case?
Many case. Two examples: 1. Selectros in CSS. Now selectors can only be element like * , E, E F, E > F and pseudo-class/pseudo-elements like: E:first-child. But we can't matche any E element ID. Atom 0.8 support xml:lang so support also E:lang(c) but there aren't any id attributes to CSS 's E#myid 2. XPointers - point some parto of document in URI/IRI for example: http://example.org/atom.xml#myid
