+/**
+ * @class AliHLTOnlineConfiguration
+ * @brief Description of the HLT online configuration
+ * This class wraps an online HLT configuration file for storage in a
+ * CDB object.
+ *
+ * Ideas:
+ * The class provides easy access to the XML tags of the configuration through
+ * an XML parser.
+ *
+ * The online configuration is translated into a tree like configuration
+ * structure. The Draw function can be used to create a graph.
+ *
+ * The xml configuration is loaded into an internal TArrayC buffer, which
+ * is automatically compressed depending on the compression level used for
+ * root file storage. Later extension will be the implementation of a custom
+ * Streamer function implementing the most efficient compression.
