Why is this marked nullable?
> Brooklyn Camp syntax for adding tags to an entity spec
> ------------------------------------------------------
>
> Key: BROOKLYN-460
> URL: https://issues.apache.org/jira/browse/BROOKLYN-460
> Project: Brooklyn
> Issue Type: New Feature
> Reporter: Valentin Aitken
> Priority: Minor
>
> Current requirement is to be able to supply String tags in an entity spec in
> YAML so it can be then retrieved via REST API with {{GET
> /v1/applications/<appId>/entities/<entityId>/tags}}.
> Example usage in a YAML blueprint:
> {noformat}
> services:
> - type: org.apache.brooklyn.entity.software.base.VanillaSoftwareProcess
> brooklyn.tags:
> - tag1
> - tag2
> {noformat}
> Please shout if you have further requirements for {{brooklyn.tags}}.
