createGovernanceZone
```
String createGovernanceZone(String userId,

Create a definition of a governance zone. The qualified name of these governance zones can be added to the supportedZones, publishedZones and defaultZones properties of an OMAS to control which assets are processed and how they are set up. In addition, the qualified names of zones can be added to Asset definitions to indicate which zone(s) they belong to.

Parameters:

userId - calling user

properties - properties for a governance zone

Returns:

unique identifier of the governance zone

Throws:

InvalidParameterException - qualifiedName or userId is null; qualifiedName is not unique

PropertyServerException - problem accessing property server

UserNotAuthorizedException - security access problem
