+/**
+ * Common interface for document storage services in the cloud. This interface
+ * supports most document services and provides some flexibility for
+ * vendor-specific features and requirements via an optional $options array in
+ * each method signature. Classes implementing this interface should implement
+ * URI construction for collections and documents from the parameters given in each
+ * method and the account data passed in to the constructor. Classes
+ * implementing this interface are also responsible for security; access control
+ * isn't currently supported in this interface, although we are considering
+ * access control support in future versions of the interface.
