Subject: [PATCH] Fix MCM and EPC missing tagpaths/color/state/priority
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MCM: was returning null for tagpath — now gets System/{mcm}/MCM09
EPC: emitEpc() was building <g> without Ignition data attributes —
now includes igAttrs (data-tagpath, data-color, data-state, data-priority)
