You can press the "Edit Extensions" button to set up the primary key.
If no such "extensions" are entered, the datasource provides the
information.
In this case, you can't see it in Maestro.
You can use the DescribeFeatureSchema call to examine the setup of a
FeatureSource:

Could you elaborate on this a bit? If I look in Maestro at the XML for a WFS
connector, or an SDF connector, or an Oracle connector, there's nothing to
suggest a primary key. So how does MapGuide know whether one exists in a
given data source?
Thanks
