Hi Xavier thanks for your solution using other layers, I'll give it a try. I thought about it also at a first place but I was afraid of the performance overhead to have potentially 4 more layers (of about 1000 features each) to achieve that. After digging in the source code, another (more complicated) solution would have been to create a custom renderer which can create symbols compositions, for example in my case a svg renderer which could attach multiple child nodes to the feature node rendered. I havent yet figured how to do that, but maybe it could be a nice feature for openlayers and I may experiment with it if I have more time :)
