"component" has a formal definition in Ada (3.2(2)); as do "subcomponent" 
and (unfortunately) "part".

OTOH, "element" and "item" are just used in one of the predefined packages, 
which is a much more informal usage. You can find this out by looking in the 
index of the LRM; terms that have definitions are indexed to those 
definitions.

While "component" is indexed to 3.2(2), "element" is just indexed to the 
containers and to storage pools (not a general term), and "item" doesn't 
appear at all. (It is only used in it's English sense.)

Summary: You can try too hard to make sense of a pattern when there isn't 
any. :-)
