[mapserver-dev] MS RFC 68: Support for combining features from multiple layers (Call for discussion)

[Jeff McKenna]

Hello Tamas,

This is a very interesting proposal.  I often have a hard time to 
picture these changes beforehand, but I am trying to now and I have a 
question: when it comes to clustering, I think a common need is also to 
label the number of clustered points...and since you'll know how many 
features are combined according to your proposal (I see 
'Cluster:FeatureCount' mentioned in the RFC) I believe we must also 
expose this clustercount in the label object.  How I am not sure, but to 
me this will be a common need.  Or is this mentioned in the RFC already?
