Summary: Ready

Two nit-level comments:

I found the formulation 'The key package error content type MUST be 
signed if the entity generating it is capable of signing it' awkward. 
Protocols break if you don't follow a MUST. As written, this says its ok 
to break the protocol. Is this, instead, really trying to say something 
about the thing that's going to evaluate the error content type (like 
"expect a signature unless you're explicitly configured to allow a lack 
of one")?

The word "above" in "Error codes above this point" is ambiguous. It can 
mean either "earlier in the document" or "with numbers greater than this 
value".
That ambiguity may be harmless (it's easy to resolve by looking at the 
referenced document), but if you want to remove it, I suggest saying 
"The error codes listed here with values <=33".
