Add new property "label" to label the source corresponding to the
output connection. When the funnel supports multi-output, this
property needs to be introduced to mark which source component a
certain output connection corresponds to.

Nope, now you have no constraints on port node properties. Please look
at how other bindings are done to add properties on endpoint node.

Don't need this.

label already has a type.
As this node is an output, aren't you labeling what the destination is,
not the "source"?
Why can't you look at the remote connection to identify what it is?
