[This is preliminary documentation and subject to change.]
HOME is the common root path name to all the namespaces specified in the NAMESPACES list. If the HOME keyword is defined, all names in the NAMESPACES list are assumed to be relative to the HOME namespace. The fully qualified namespace path can be derived by adding as a prefix the HOME namespace to each of the names in the NAMESPACE list. If the HOME keyword is not defined, all namespaces in the NAMESPACES list are assumed to be fully qualified.
Example: HOME=Root\Redmond;NAMESPACES=Fred
The fully qualified namespace is Root\Redmond\Fred.
