When you share an item and it links to other items, which of the linked items are implicitly shared and which aren't?

The high-level answer is that it should be specified by the Kind's content model. When specifying a non-scalar attribute of a Kind, the attribute's sharing policy should be specified. [ BrianDouglasSkinner, is this a data model feature request? If so, can you communicate this to the data model team?]

Here is a more detailed analysis, with general guidlines for deciding which links should be implicitly shared:

Kind of link	Share Link?
Contained notes	Yes
Paired item via stamping	Yes
Other items in same collection including threads	No
Conversation items	Yes
User-defined item link attribute	To be determined when we discuss user-defined attributes
Reminders (in calendar)	No
Email attachment	Yes

The last two are examples of domain specific Kind issues
