Description:
Providing a mechanism to seperate facilities from components at the container specification
level is desirable.  

This would ensure:

  (a) clear separation of facility dependencies
      from component dependencies

  (b) elimination of the exposure of the compositon
      api and spi from regual components

Achiving the above would require some additional classloader management - in particular, delegation
from a container facilities classloader to a parent container's facilities classloader.

In addition - we would need to include a mechanisms for a component to declare the assumptions
it has concerning facilities.
