[mapguide-users] Maestro Api runtime map selection

[Kenneth Skovhede, GEOGRAF A/S]

Unfortunately the MaestroAPI cannot create datastores,
or update/insert features because this is not exposed in the MapGuide 
http API.
You have to use the MapGuideDotNetApi.dll or similar to access those 
functions.

As a workaround, you can instead use an SQLite database, which you can 
create
and upload to a FeatureSource. This enables you to control the database 
layout,
and also allows you to connect to the database with standard tools
(such as ODBC or System.Data.IDbConnection), for updates and inserts.

There seems to be a bug regarding Selections (selection support was 
introduced recently).
You can get the selection this way until the bug is fixed:
selection = new OSGeo.MapGuide.MaestroAPI.Selection(rtMap, 
rtMap.CurrentConnection.GetSelectionXml(rtMap.ResourceID));

This should also reveal how to get the selection document directly.

The ToString() function is not overloaded, so when using the selection 
object you have to use ToXml() instead.
I will fix this too.
