XML Schema usage submission

I would like to contribute an XML Schema, LandXML, to the usage section of the W3 XML Schema page. 
 
The LandXML schema is defined, maintained and hosted by LandXML.org, an open organization for Land Development/Transportation Industry organization. LandXML models the civil engineering design data used to create new residential subdivisions and build new roads.
 <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
Schema file name   : LandXML-1.0.xsd
Schema namespace: http://www.landxml.org/schema/LandXML-1.0
Schema location     :  <http://www.landxml.org/schema/LandXML-1.0/ LandXML-1.0.xsd> http://www.landxml.org/schema/LandXML-1.0/ LandXML-1.0.xsd
 
Schema Description: LandXML is an emerging XML data standard for civil engineering and survey data used in the Land Development and Transportation Industries. LandXML facilitates open data exchange between software applications, provides an electronic format for design data project submission and provides a format suitable for long term archival.
 
More Information:
 
LandXML has a reasonably complex content model has evolved from a simple XDR schema, ( http://www.landxml.org/schema/landxml-0.01/LandXML-0.01.xml <http://www.landxml.org/schema/landxml-0.01/LandXML-0.01.xml> ), over the past 3 years to use most of the features available in the latest XML Schema recommendation. The web site for the schema is http://www.landxml.org <http://www.landxml.org> , where you will find the schema, documentation, sample files and sample applications. There is also a list of world-wide participants on the http://www.landxml.org/org.htm <http://www.landxml.org/org.htm>  page.
 
LandXML is emerging as the XML standard for the Land Development and Transportation Industry by US Department of Transportation, AASHTO (American Association of State Highway Officials) and the Federal Highway Administration. LandXML is also being used and recognized internationally by Land Information New Zealand. LandXML also has strong support in the software vendor community http://www.landxml.org/landxmlapps.htm <http://www.landxml.org/landxmlapps.htm> .
 
Please let me know if any other information is required.
