[xsd-users] Problem linking with VS 2008

[Thomas Dobroth]

Boris,

The below modifications will not work.  The w3.org namespace is not 
opened as xs: in either KML or the Google extensions.  It's opened as an 
"in use" namespace.

/<schema targetNamespace="http://www.google.com/kml/ext/2.2" 
elementFormDefault="qualified" version="21092011BETA" 
xmlns="http://www.w3.org/2001/XMLSchema" 
xmlns:gx="http://www.google.com/kml/ext/2.2" 
xmlns:kml="http://www.opengis.net/kml/2.2" 
xmlns:atom="http://www.w3.org/2005/Atom" 
xmlns:xal="urn:oasis:names:tc:ciq:xsdschema:xAL:2.0">
<!-- Import the language we are extending: OGC KML 2.2 -->
<import namespace="http://www.opengis.net/kml/2.2" 
schemaLocation="ogckml22.xsd"/>
/
