== Overview ==

This change adds a new version of the DWG Load Procedure resource schema. 

== Motivation ==

Autodesk !MapGuide Studio will start using a new DWG load procedure XML document.  Because the DWG load procedure document is stored in the repository the schema must be made available to the server. 

== Proposed Solution ==

Copy the contents of LoadProcedure-1.0.0.xsd to a new file, LoadProcedure-1.1.0.xsd.  Set the version to 1.1.0 and modify the DWG load procedure portion of the file.  The rest of the load procedures are unchanged.  Add LoadProcedure-1.1.0.xsd to the Common/Schema folder.  This is enough to get the server to store DWG load procedures in the new format in the repository.  Below is the new DWG load procedure related schema.
