I'm feeling positive about PaceServiceError, but I have a question: why does it need to use a new custom-built HTTP verb? Why don't we just specify that you POST to the ServiceError URI two name-value pairs, CGI style, either in the URI or the body?
Name Value resource the URI where the problem is problem free-text description of the problem, no markup
e.g. POST with no body to http://example.com/service/error?name=http://example.com/feed/ 315135&problem=not%20well- formed,unbalanced%20tag%20line%2041%20col%20118
