+/**
+ * Resolves the MimeType and Resource type of the resource to match the file
+ * name used in the Symbian side. This class is following the behavior of the
+ * Symbian class XnInstallationHandler.cpp in ...Xuikon\UIManager\src\
+ *
+ * In Symbian, MimeType is TDataType that has TBuf8 and TUid. The constructor
+ * taking a descriptor of TDataType is as follows:
+ *
+ * If descriptor begins with "x-epoc/x-app", identifying data as a native
+ * Symbian type, then the associated UID is set to the UID value which is
+ * expected to follow the characters "x-epoc/x-app". If no sensible UID can be
+ * extracted from the characters following: "x-epoc/x-app", then the associated
+ * UID is set to KNullUid.
+ *
+ * Else Uid is set to KNullDesc and the descriptor is the descriptor given in
+ * parameter.
+ *
+ * In ...Xuikon\UIManager\src\XnInstallationHandler.cpp
+ * (ImportCompatibleResourcesL) MimeType is constructed using the Descriptor
+ * that is parsed using file's name extension. Descriptors beginning with
+ * "x-epoc/x-app" aren't used so TUid part is not implemented. Some of the types
+ * are left empty in XnInstallationHandler.cpp. This represented as
+ * EMPTY_MIME_TYPE
+ *
+ * Resource types are defined in Symbian side class XnResource.h
