HDATA — GET operation on baseURL/root.xml needs explicit MUST in the requirement

The requirements reads as "This operation returns an XML representation of the current root document, as defined by the HRF specification."

It can be inferred from this requirement that this is an implied “SHALL” or “MUST” mandatory requirement not an implied SHOULD/RECOMMENDED.

Likewise, not defined if the baseURL does not exist, which should return 404 status code as done with similar HTTP operations. This would then be consistent with requirement in section 6.2.

Revised requirement:

This operation MUST return an XML representation of the current root document, as defined by the HRF specification.
If there is no HDR at the base URL, the server SHOULD return a 404 - Not found status code.

Resolved with 17234.
