Support for SoH is quite limited, i.e., these attributes are really just
hardcoded in src/eap_peer/tncc.c. The TNC implementation itself supports
plugins, but not for SoH use.

What kind of use case do you have in mind for SoH? It looks pretty
Microsoft specific to me and it is somewhat difficult to see good
justification for extending the minimal SoH implementation when rest of
TNC have much less OS dependent and restricted design..
