Subject: XML Instance --> XML Schema ?

Hello,
I have studied the whole XML Schema on W3C site. There is still something confusing \
me.
The XML Schema: po1.xsd
<schema xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:po="http://www.example.com/PO1"
targetNamespace="http://www.example.com/PO1"
The XML Instance: po1.xml
<schema xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:po="http://www.example.com/PO1"
targetNamespace="http://www.example.com/PO1"
I understand that the targetNamespace references to the customized XML Schema, which \
has to be written in the po1.xsd and in the po1.xml files. But how can the parser \
looks after my customized XML Schema which is saved in the po1.xsd file? How does it \
know where the XSD file is located? As far as I understood the Namespaces the URI of \
a Namespace is just there to mention a unique namespace. The Parser would not look \
after what's behind the URI.
Could someone help me to understand this? :o)
Houman
