#pod
#pod These objects represent paragraphs in the JMAP response.  That is, if your
#pod response is:
#pod
#pod   [
#pod     [ "messages", { ... }, "a" ],      # 1
#pod     [ "smellUpdates", { ... }, "b" ],  # 2
#pod     [ "smells",       { ... }, "b" ],  # 3
#pod   ]
#pod
#pod ...then #1 forms one paragraph and #2 and #3 together form another.  It goes by
#pod matching client ids.
#pod

#pod sentence doesn't have that name, an exception is raised.
