feature</link> and the

on before you parse a document.

+ <p>According to the XML Schema specification, an instance document might have
+more than one <jump href="http://www.w3.org/TR/xmlschema-1/#key-vr";>validation
root</jump> and
+it specifies that the
+<jump href="http://www.w3.org/TR/xmlschema-1/#cvc-id";>ID/IDREFS</jump> must be
+unique within the context of a particular validation root, meaning that a
+document may contain multiple identical ids. In this case, the output
+of getElementById() is unspecified. On the other hand, if the document root is
+a validation root of the document, getElementById() should work as expected.
+During loading there is no way (currently) so specify validation roots
+in Xerces, thus Xerces always treats the document root as validation
+root.
+However, in the future it is possible to give XPath expression
+specifying at what elements validation should start. For example:
+
+<documentRoot>
+<validationRoot_1>Some Data</validationRoot_1>
+<validationRoot_2>Some Data</validationRoot_2>
+<documentRoot>
+
+In this case, ID/IDREF must be unique in the scope of validationRoot_1
+or in scope of validationRoot_2, however ID/IDREF table might not be
+unique for documentRoot.
