Bertrand Delacretaz commented on CLEREZZA-460:
----------------------------------------------
Using bundle startlevel to define service priorities is very unusual, I'd
recommend using the service ranking instead.
Sorting the ServiceReference objects that a ServiceTracker returns is
sufficient to take that value into account, see
http://www.osgi.org/javadoc/r4v42/org/osgi/framework/ServiceReference.html
> Use whiteboard pattern for Renderlets

> The current mechanism for renderlets is overly complex. Instead of describing
> renderlets in a graph rendelets should be services that have properties
> indicating the rdf type and the mode-pattern they handle.
> The priority for selecting renderlets should be:
> - type, according to type-priority list
> - length of regex math (the matching regex with the most alphanumeric
> characters wins)
> - startlevel of the bundle providing the service
