>(1) What are "composed objects"? (don't recall that terminology)
Composed objects are those objects that related to RegistryObject box 
via a relationship with a solid diamon in Figure 1 in ebRIM. Composition 
is decsribed in ebRIM somewhere and its definition is as described in 
UML. Composed objects are part of another object and cannot live 
independent of their parent composite objects. In ebRIM 2.5 
Classifications, ExternalIdentifiers and Slots are examples  of composed 
objects within a RegistryObject.

>(2) Is this covered by our Cursor Support feature?
The issue sent by  Mei is not addressed by our Cursor Support feature. 
The issue is that a client must issue two separate registry requests one 
to a get a RegistryObject and another to get its ExternalLinks. Where as 
when a client gets a RegistryObject today all its Classifications are 
included in same response.

I have also found that ExternalLink implementation is trickier because 
it is handled different from Classifications etc.

I tend to be very supportive of the idea of making ExternalLink be a 
composed object within ebRIM and woudld be willing to do this in our 
next version (2.6).
