Subject: [PATCH] Support rendering of patternProperties
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the pattern is ignored as there is always only one
pattern in current definitions,
and the pattern is clear with the descriptions.
First step to render `m.receipt` event
