Part I: Is it possible to use Experience Manager (specifically to make *existing content modifications) from an application that does not use content delivery (CDA) binaries. For example, from static html files that are published to the file system?
Part II: If this is technically feasible, would it also be possible to use XPM from a SPA app (e.g. AngularJS) that uses a client-side library to fetch content via OData webservice from client side?
Part III: If technically feasible, are there any license implications regarding the use of XPM from an application that does not leverage content delivery license?
