Describing headers accepted by a supported operation

Hi,

For a recent project, I've trying to describe an LDP application using the
hydra vocabulary. I can describe most of the stuff using supported
classes/operations/properties, expects, returns, statusCodes, etc.

Trying to go even a bit more further, I was wondering whether there was a
way to describe the information about the expected or supported headers.
For example, If I want to tell a client that it can send a Slug header [1]
or a Prefer header for a particular supported operation, is it possible
with Hydra? I also found the issue [3] of Hydra console which is about
adding a similar functionality to the console but I couldn't find how a
client can discover those information.

Best Regards,
Nandana
