//The model can be called like:
//http://localhost:8081/org.panlab.software.ws.repos.m2m/repo/PanlabServices.office2
//The extension here of the webservice (eg .office2) must be registered
//also in the language (ie in officedl) under the extension point org.eclipse.xtext.extension_resourceServiceProvider
//uriExtension=office2, class= the same as the officedl extension
//So, as a result the response (which is an instance of the ecore model) can be seen inside the DSL

//Since there is a penalty here from the repository, caching can be used 
//(i.e. saving somewhere on the server the whole ecore model) instead of making
//on the fly transformation or use an Office Proxy
