i am asking this in the context of thomas weiss blog on
from the blog :
"Source code plug-ins are unnamed. You create a source code plug-in by assigning a (simple) enhancement implementation to an enhancement point. In turn, this means that a (simple) enhancement implementation can only be assigned once to an enhancement point. Otherwise the identity of a source-code plug-in would be blurred."
so if we can assign enhancement implementation only once to enhancement point,how can we create second source code plug-in to same enhancement point?
