<< sorry my last mail was sent incomplete>> Hello All, We would like to solicit some feedback about two points in context to capabilities: 1. Capability Instances: Currently the document instantiates two capabilities viz, a) Capability Indicators (which can be used to carry flags such as support of 6LoRH) b) Routing Resource capability which indicates total RIB capacity the node has. This should be useful for DAO Projection. Do you think we should add Neighbor Cache capacity indication as well and what would be the use-case? 2. Regarding the use of 'G' (global) flag on per capability basis: Do we need an explicit 'G' flag? We already have a flag (C-copy) which indicates that nodes have to copy the cap if they don't understand the cap. A global capability from the root can be advertised with this bit set. Nodes understanding this cap will anyways know how to handle and nodes not understanding it will copy it based on the 'C' flag. Thus not requiring another 'G' flag.
