TOSCA should specify what to use in the accept Header for HTTP REST requests.

TOSCA does not address wire protocols for making REST requests for TOSCA documents.

For example, what should the accept type be in the following situations:

• CSAR
• Definitions Document
• Schema documents

One could infer that for the CSA it would be application/tosca-csar or application/csar
For definitions documents, it could be application/xml.

However, in the second case, this would be insufficient according to intended HTTP accept header usage.

This issue perhaps should be linked to https://tools.oasis-open.org/issues/browse/TOSCA-7

For some background on Accept type, the following article is interesting:
