A unique ID question ?

[DuCharme, Robert]

>I was wondering if the value of an ID attribute has to be unique within a 
>document or only within a fragment.

>From the "ID" validity constraint in section 3.3.1 of the spec
(http://www.w3.org/TR/REC-xml#sec-attribute-types): "A name must not appear
more than once in an XML document as a value of this type; i.e., ID values
must uniquely identify the elements which bear them."
