Not all the XML schema parsers support the complete XML schema draft. Most
of them have just implemented part of it. I dont know about the ones you are
using, but I found XMLSpy to be the most advanced with the implementation of
the latest draft. You can download XMLSpy at htp://www.XMLSpy.com

The <sequence> element is not needed here since that is already the default
in XML schema. You also specify a type for the storelocation element, and
then you define a simpletype enumeration for this element. The way you did
it is not correct. This XSD file should have been looking like this:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/1999/XMLSchema">
  <xsd:element name="StoreName">
           <xsd:element name="StoreId" type="xsd:string"/>
	   <xsd:element name="StoreLocation">
	     <xsd:simpleType base="xsd:string">
	        <xsd:enumeration value = "USA"/>
		<xsd:enumeration value = "Europe"/>

If you open your XML file with this XML schema in XMLSpy, you will get the
errors you expect.

I hope this helps
