Giving something a unique address is arguably 100%
orthogonal to validity. The only reason we mix these two
up is that IDs were one of the many things that got
thrown into the DTD basket by SGML.

The standard means - DTDs and schemas - are overwhelingly
concerned with validation. This is a good and useful
thing, but it in a considerable proportion of applications
it is not applied at run-time. And being able to find the
node to which a pointer applies is a function which can
exist entirely independent of validation. QED. -Tim
