[fdo-internals] PATCH: Connection-Properties of various providers

[Aaron Pieler]

Hello everyone,

In an attempt to unifiy the behaviour of the connection properties i made
following changes to the providers:

ODBC:
* DataSourceName: IsRequired = true
* ConnectionString: IsRequired = true
* GenerateDefaultGeometryProperty: IsEnumerable = true; EnumerableValues=
true, false

SHP:
* DefaultFileLocation: IsRequired = true

WFS, WMS, King-Oracle:
* Password: IsProtected = true;

SQL Server Spatial:
* ConnectionString:  IsProtected == false (Why is the ConnectionString
currently handled like a password? Is this really necessary?)

OGR:
Here I am not sure and didn't change anything so far. 
Currently IsEnumerable is set to false. Why does the OgrProvider not handle
this like the SDF-Provider does?


Does someone have an objection against something or comments about
something?
Would these changes do harm to applications currently using FDO?

Thanks
