By Nested RSLs, I mean:
- MyLibrary is using TweenMax as a library with LinkType = Extended, and
- MyApplication is using both MyLibrary and TweenMax as libraries with LinkType = RSL
I think you meant "External" when you said "LinkType = Extended".
This isn't really nested RSLs. By linking a library as External you have made that library's RSL dependent on the External library's RSLs.
In your example MyLibrary is compiled with TweenMax as an external library. This means MyLibrary's RSL is dependent on TweemMax's RSL. The dependency requires MyApplication to load the TweenMax RSL before the MyLibrary RSL.
