RE: draft-ietf-ltans-dssc-00 comments --constraints--



Hello Susanne, 

yes, I think it should be sufficient to give an example of current
constraints in the draft. 
We could also define an OID e.g. to define specific constraints: 
OID for "larger key is always more secure than less"

What other constraints do you have in mind?

Tobias
