Jessica,

My comment was only about the changes that will be available in 4.0 from
source code perspective, where its easy to discover integration points and
develop one. However, allocators implementation guide is okay but adapter
framework guide is pretty old and does not reflect all the integration
points that will be available in 4.0. This needs an update. Should I open
a doc bug with the details on whats required?


Thanks,
Murali
