    /** creates a connection which can be used for the rowset given

        The function tries to obtain a connection for the row set with the following
        steps (in this order):
        <nl>
            <li>If the rowset already has an ActiveConnection (means a non-<NULL/> value for this property),
                this one is used.</li>
            <li>If row set is part of a database form document (see ->isEmbeddedInDatabase),
                a connection for the respective database is used.</li>
            <li>If in the parent hierarchy of the row set, there is an object supporting
                the XConnection interface, this one is returned.</li>
            <li>If the DataSourceName property of the row set is not empty, a connection for this
                data source is retrieved.</li>
            <li>If the URL property of the row set is not empty, a connection for this URL is
                retrieved from the driver manager.
        </nl>

        The calculated connection is set as ActiveConnection property on the rowset.

        If the connection was newly created by the method, then
        the ownership of the connection is delivered to a temporary object, which observes the
        row set: As soon as a connection-relevant property of the row set changes, or as soon
        as somebody else sets another ActiveConnection at the row set, the original
        connection (the one which this function calculated) is disposed and discarded. At this
        very moment, also the temporary observer object dies. This way, it is ensured that
        there's no resource leak from an un-owned connection object.

                        instance will not have the ownership, since in this case it's assumed
                        that there already is an instance which has the ownership.</li>
                    <li>If the connection was newly created, then the returned SharedConnection
                        instance will have the ownership of the XConnection.</li>
