When i tried to draw some network diagram with nwdiag, it results in Syntax error if i have hyphens in network or node id, such like :
```
@startuml
nwdiag {
network network1 {
address = "192.0.2.0/16"
node-1 [address="192.0.2.4"];
node2 [address="192.0.2.2"];
node3 [address="192.0.2.3"];
}
}
@enduml
```
When the hyphens are removed or replaced with underscore, it works.
The problem for me is that the network i am not trying has hyphen/dashes in its network or node names.
Anyone can help me to draw it without changing real-life network/node names ?
