HDATA — GET operation on non-existing baseURL or sectionpath SHOULD return 404 status code

6.4.1 defines a GET with a 200 for success but doesn't address the not found case as defined in other GET operations (e.g. 6.2.1 and 6.5.1)

The implied requirement here is the following, which should be added to the section:

If baseURL does not exist or no sectionpath of name sectionpath exists, the implementation SHOULD (or MUST) return a HTTP status code 404.

This would then be consistent with section 6.5.1 for an invalid/non-existing documentname in the URL
