+== Overview ==
+
+The purpose is to add support to additional parameters and bit-depth variations to image formats. 
+
+Currently, WMS Provider supports four image formats: image/png, image/jpg, image/tif, image/gif. They are defined as:
+enum FdoWmsOvFormatType{
+
+    FdoWmsOvFormatType_Png = 0,
+    FdoWmsOvFormatType_Tif,
+    FdoWmsOvFormatType_Jpg,
+    FdoWmsOvFormatType_Gif
+};
+
+This enhancement will support additional parameters and bit-depth variations such as:
+
+image/png; PhotometricInterpretation=PaletteColor
+image/png; PhotometricInterpretation=RGB
+image/png; mode=24bit
+
+
+== Proposed Solution ==
+
+WMS Override API will accept a string instead of the enumeration for image format. It will only accept server defined format strings that contain ‘png’, ‘tiff’, ‘jpeg’ or ‘gif’ in their definitions. 
+
+This section outlines the necessary code changes in the unmanaged and managed code.
+
+=== Unmanaged Code ===

+    /// 
+    /// \return
+    /// Returns nothing.
+    /// 
+    FDOWMS_API void SetFormatType(FdoString* value);
+...
+}
+}}}
+
+=== Managed Code ===

+}}}
+
+
+== Implications ==
+
+This change will not cause any side-effects, nor any compatibility problems. 
+
+== Test Plan ==
+
+Existing unit tests will be expanded to test those changes.
+
+== Funding/Resources ==
+
+Autodesk to provide resources / funding to update WMS Override API.
