Hi Andy,
Thanks for the fast answer!
A clarification is possibly needed: what we are discussing in the
Federated
Cloud group is not what happens when multiple headers are present, but
if a single
Category header element can be written on multiple lines. i.e. if the
following
representation of a category, taken from page 20:
Category: storage;
scheme="http://schemas.ogf.org/occi/infrastructure#";
class="kind";
title="Storage Resource";
rel="http://schemas.ogf.org/occi/core#resource";
location="/storage/";
attributes="occi.storage.size{required}
occi.storage.state{immutable}";
actions="http://schemas.ogf.org/occi/infrastructure/storage/action#resize
...";
Is acceptable in the answer as is, with the newlines between elements
and the
indentation, or if it is supposed to be on a single line.
Thanks in advance,
Vincenzo
