That is not how I understood Jeroens answer (or the NML spec), but I could 
be wrong.

>From GFD.206 (the NML spec):

* The encoding attribute defines the format of the data streaming through the Port

* labeltype to refer to a technology-specific labelset, e.g. a URI for VLANs

Doesn't sound like the same. If the encoding is ethernet, there are 
options for no label (trunk), vlan, and q-in-q (s-tag/c-tag). I could 
imagine that certain types of labels might be available on different 
encodings.

Currently we don't really use encodings in NML for NSI, but they can be 
specified on port(groups) and link(groups).
