I have one confusion regarding the ID
ID has to be unique for a particular element or for whole of the document.

Suppose i have a <Teacher> element with a ID attribute TeachID
and a
<Student> element with a ID attribute StudentID

now is it legal to use same id for TeachID and StudentID
<root>
<Student StudentID="001"/>
<Student StudentID="002"/>
<Student StudentID="003"/>
<Teacher TeachID="001"/>
<Teacher TeachID="002"/>
<Teacher TeachID="003"/>
</root>

Andy,
ID MUST be unique in an xml document. It does not matter if ID attribute is present in different elements.

Good Luck,
Satish.
