18.104.22.168 Referencing External Types
The automation IDL extensions allow elements defined inside an automation scope to reference types defined in an external automation type library. This is done through the use of the importlib statement:
oa-importlib = kw-importlib LWSP "(" LWSP string LWSP ")" LWSP ";"
The string specified in the importlib statement is an implementation-specific string<50> that MUST allow an automation type library to locate the definitions of referenced types that are defined in another automation type library.
