This section defines the sourceIds that are valid for passing to getFields and setFields.  This list is complete, but please note that your greenID account may be configured with a subset of these sources; a list of valid data sources for your greenID account is always available via a call to getSources, or by inspecting thesourceList element returned by any call to the API.  If a source does not appear in the sourceList, then you it cannot use itbe uses (it will give an InvalidSourceIdFault).

Data Source Versions

For every data source, greenID maintains a version number, which is returned in each source element in the sourceList element, returned from every call to the API.  The version number is used to track changes to the field structure for the data source.  If the field structure changes, for example by adding a new required field, then the version number will be incremented.
