Blocking/Filtering BPDUs

Using an ex4300 and ELS style config, I have configured interface ranges, say access-vlan4, and I have configured RSTP on that range:

rstp {
interface access-vlan4 {
edge;
}
bpdu-block-on-edge;
}

also block on edge to try to help prevent switching loops.  Let's say that one particular port (in that interface range) we'd like a STP running switch plugged in.  We want to just discard any BPDUs inbound and not block that port but let normal traffic pass.  What would be the best way to configure that, in the ELS format?
