/** implements a component which allows browsing the data sources registered on the system.

	<p>
	This service implements a user interface for browsing data sources registered on the
	<type scope="com::sun::star::sdb">
	DatabaseContext
	</type>
	instance of the system.
	</p>

	<p>
	It is possible to navigate through all the data sources, it's queries and it's tables.
	The queries/tables can be displayed in a grid-like view, where functionality for searching,
	sorting, filtering, and such is provided.
	</p>

	<p>
	Usually, you won't instantiate this service directly, instead you use the dispatch mechanisms
	of the application framework to load the URL <b>.component:DB/DataSourceBrowser</b> into an arbitrary
	frame. This should involve a
	<type scope="com::sun::star::sdb">
	ContentLoader
	</type>
	service, which creates and initializes
	the browser.
	</p>

	<p>
	Some aspects of the browser can be controlled from outside, eg.,
	it is possible to dispatch a sort or filter
	request, if a table or query is being displayed.
	</p>

	<p
	>The communication between the browser and external instances works in two ways.
	<br/>
	The way <em>in</em> is provided by the
	<type scope="com::sun::star::frame">XDispatchProvider</type>
	interface the service exports (Please see below for more details on this).
	<br/>
	The way <em>out</em> works in another way. There are several URL's which an external
	instance can provide dispatches for (usually by implementing a
	<type scope="com::sun::star::frame">XDispatchProviderInterceptor</type>
	for the parent frame of the browser), thus indicating that the browser should provide special functionality.
	<br/>
	In this case, the browser displays and maintains some additional slots (to be more concrete: toolbox items), which,
	upon triggering, call the
	<member scope="com::sun::star::frame">XDispatch::dispatch()</member>methodoftheobject
	provided by the external instance.
	</p>

	<p>
		In particular, the supported URL's for communicating to an external instance are:
		<ul>
			<li><b>.uno:DataSourceBrowser/InsertColumns</b>
			<br/>
			Available whenever an external instance provides a dispatcher (
			<type scope="com::sun::star::frame">XDispatch</type>)
			for this URL.
			<br/>
			Enabled, if at least one row in the grid view of a table or query is selected.
			<br/>
			It is the task of the external instance to provide functionality for this URL, but usually it is used
			to implement some kind of "Data To Text" functionality.
			<br/>
			</li>
			<li><b>.uno:DataSourceBrowser/InsertContent</b>
			<br/>
			Available whenever an external instance provides a dispatcher(
			<type scope="com::sun::star::frame">XDispatch</type>
			) for this URL.
			<br/>
			Enabled, if at least one row in the grid view of a table or query is selected.
			<br/>
			It is the task of the external instance to provide functionality for this URL, but usually it is used
			to implement some kind of "Data To Fields" functionality.
			<br/>
			</li>
			<li><b>.uno:DataSourceBrowser/FormLetter</b>
			<br/>
			Available whenever an external instance provides a dispatcher (
			<type scope="com::sun::star::frame">XDispatch</type>)forthisURL.
			<br/>
			It is the task of the external instance to provide functionality for this URL, but usually it is used
			to implement some kind of "Form Letter" functionality.
			<br/>
			</li>
		</ul>
	</p>
	<p>For all kinds of URL's, the parameters supplied during dispatching build up a <type>DataAccessDescriptor</type>,
	where the following properties are present:
	<ul>
		<li><member>DataAccessDescriptor::DataSourceName</member></li>
		<li><member>DataAccessDescriptor::Command</member></li>
		<li><member>DataAccessDescriptor::CommandType</member></li>
		<li><em>optional</em> <member>DataAccessDescriptor::Selection</member></li>
		<li><em>optional</em> <member>DataAccessDescriptor::BookmarkSelection</member></li>
		<li><em>optional</em> <member>DataAccessDescriptor::ResultSet</member></li>
	</ul>
	</p>
	<p>The default for <member>DataAccessDescriptor::Selection</member> is to contain bookmarks, if not specified
	otherwise by <member>DataAccessDescriptor::BookmarkSelection</member>.</pr>
	</p>

			meaningful together with the other parameters specifying the object to display.</li>

            <li><b>CommandType</b><br/>

            is a boolean value (defaulting to <TRUE/>), which specifies whether to enable the data source browser
