[xwiki-devs] Nested spaces and right service implementation

Hi, I have almost finished writing a new right service implementation and have some questions about nested spaces. I am using the EntityReference classes for representing the document hierarchy, with the addition for using the main wiki as the parent of a virtual wiki. XWikiRightServiceImpl is using the parent field in the space's preferences to form a space hierarchy. The EntityReference classes support a list of spaces, but this does not seem to be implemented yet. Can a right service implementation assume that the nested space hierarchy was resolved externally and was inserted into the DocumentReference as a list of spaces? Will the list of spaces in an EntityReference correspond to following parent fields in the space preferences or does a right service implementation need to resolve these parent fields for backwards compliancy?
