Geometry from joined feature source not selectable

[ronnielouie]

The DescribeSchema API produces a list of all properties from all feature classes for a particular feature source. This includes the geometry properties from the joined feature source for an extension (join) feature class. As only the geometry from the primary feature class for join is supported, presenting the geometry from the joined secondary feature class as an available option can be confusing and in fact not applicable. To resolve this issue, the geometry properties from the secondary class will not be returned from DescribeSchema, which effectively limits the geometry selection to those available from the primary class.
