  /**
   * It helps DataSource::Generic working in different "operation modes".
   *
-  * <ul>
+  * <b>Modes:</b> (these are proposals, more or less...)
   * o Pass-Through-Reference: php Object will get passed through all layers
   * o Pass-Through-Memory: reference to a memory area will get used
-  * x Build-Locator: build locator from datasource-type and adapter-type
+  * + (x) Build-Locator: build locator from datasource-type and adapter-type
   * o Use-Locator: directly use DataSource::Locator instance passed in
   * o Merge-Locators: merge metadata of two or more DataSource::Locator instances
   * o Build-AutoLocator: use global constants making up our metadata
-  * </ul>
-  *
   *
   * <b>It can/should contain:</b>
   * (flexible, just some parameters are required for each operation mode)
-  * <ul>
   * o an oldschool "dsn"-string (e.g. for rdbms-connection via PEAR)
-  * x name of a Proxy module to use to *wrap/hide* the connection/transport-layer
+  * + (x) name of a Proxy module to use to *wrap/hide* the connection/transport-layer
   *   (e.g. DataSource::Proxy::XMLRPC via DesignPattern::RemoteProxy)
-  * x metadata (a hash) directly describing *where* to connect to (e.g. 'Host', 'Port')
+  * + (x) metadata (a hash) directly describing *where* to connect to (e.g. 'Host', 'Port')
   * o an instance of an already instantiated arbitrary datasource handler (e.g. 'source')
   *   this will get propagated (pass-through-mode)
   * o a datasource-type (of 'rpc|mysql|csv-file|xml-file')
   *   this will be mapped to a module name and used as a *Proxy*
   *   by the DataSource::Generic at runtime
-  * x an adapter-type (of 'phpHtmlLib|pear')
+  * + (x) an adapter-type (of 'phpHtmlLib|pear')
   *   this will be mapped to a module name and used as an *Adapter*
   *   by the DataSource::Generic at runtime
   * o names of global constants where to find these informations
   * o datasource-type ('rpc|csv-file|...') <-> datasource-family ('orm|rdbms|odbms')
-  * </ul>
-  *
-  *
-  * <b>It can do</b>
-  * <ul>
-  * # builds a larger locator from a minimum of information passed in via constructor-arguments
-  * o direct fallback mode to some predefined constant names if locator is empty and above method fails
-  * o direct fallback mode to some predefined values if just *everything* fails
-  * </ul>

+  * - builds a larger locator from a minimum of information passed in via constructor-arguments
+  * - direct fallback mode to some predefined constant names if locator is empty and above method fails
+  * - direct fallback mode to some predefined values if just *everything* fails
   *
   * <b>How to use?</b>
   *
   * Pass an array holding "locator metadata" to the constructor.
   * This module takes care of the rest.
-  *
   * Pass an array to the constructor: (e.g.)
   *
-  *  1. for doing rpc-calls....
+  * <pre>
-  *    <code>
+  *    // 1. for doing rpc-calls....
   *    $locator = array(
   *      datasource_type => 'rpc',
   *      [adapter_type => 'phpHtmlLib',]
-Line 106
+Line 166
   *    );
   *    $source = ne w DataSource::Generic($locator);
   *    $this->set_data_source( &$source );
-  *    </code>
+  * </pre>

+  * <pre>
-  *  2. [proposal] for common/oldschool datahandles....
+  *    // 2. [proposal] for common/oldschool datahandles....
