 == Proposed Solution ==
 
+=== Schema, Class and Property Definition ===
+
 ApplySchema need not only support adding, modifying but also support deleting schema elements. So we need a method to mark the schema element for deletion. The method Delete() will be added to classes MgFeatureSchema, MgClassDefinition, MgPropertyDefinition for it.
+
+{{{
+/// \brief
+/// Contains one or more feature class definitions, which specify the structure
+/// of feature data in a datastore. 
+class MgFeatureSchema: public MgNamedSerializable
+{
+PUBLISHED_API:
+    ......
+    /// \brief
+    /// Marks the schema for deletion.
+///
+    /// \return
+    /// Returns nothing.
+    void Delete();
+};
+
+/// \brief
+/// Defines a feature class belonging to a schema. 
+class MgClassDefinition: public MgNamedSerializable
+{
+PUBLISHED_API:
+    ......
+    /// \brief
+    /// Marks the class for deletion.
+///
+    /// \return
+    /// Returns nothing.
+    void Delete();
+};
+
+/// \brief
+/// Defines the base class for the concreate property definition classes which
+/// are used to create data, geometric, object, and raster property definitions. 
+class MgPropertyDefinition: public MgProperty
+{
+PUBLISHED_API:
+    ......
+    /// \brief
+    /// Marks the property for deletion.
+///
+    /// \return
+    /// Returns nothing.
+    void Delete();
+};
+}}}
+
+=== Changes to Feature Service ===
+
+Feature Service will be extended to add one method to apply a schema.
+
+{{{
+class MgFeatureService : public MgService 
+{
+PUBLISHED_API:
+    /// \brief
+/// Creates or updates a feature schema within the DataStore. 
+///
+    /// \param resource (MgResourceIdentifier)
+    /// A resource identifier referring to a feature source.
+    /// \param schema
+    /// Input schema to be created or updated.
+    ///
+    /// \return
+    /// Returns nothing.
+    ///
+virtual void ApplySchema(
+MgResourceIdentifier* resource,
+MgFeatureSchema* schema) = 0;
+};
+}}}
