[occi-wg] OCCI Link question

[florian.feldhaus at tu-dortmund.de]

Hi Ralf,

thanks for the clarification. I was expecting this, but I didn't read the
ABNF properly. Could we add this to the OCCI HTTP Rendering document in a
future iteration (maybe just extending the existing example for Link
inline creation with a mixin)? I tried to create an issue in GridForge
once, but I couldn't find a button which said "create issue". If someone
helps me with creating issues (maybe after the move of the OGF
infrastructure is completed), I will put it into GridForge.

Cheers,
Florian
