A Domain provides a method of grouping wiki nodes by problem or information domain; nodes that belong to different domains may have the same name. In the future, domains may also be used for fine grained access control restrictions for individual nodes. See Domain Privileges for more information.
Since there would be multiple namespaces with the domain system, it becomes necessary to expand the reference syntax to accommodate references to nodes that are in another domain, and to domains themselves.
A domain's "front page" topic would be a sub-topic with the same label as the domain.
{Node Topic}
{Domain : Node Topic}
{Domain :}
This change would signify a new major-version update.
This node is strictly a proposal, and has been scheduled for implementation in Version 3.0.
