[SI-LIST] Emissions radiated from Quartz Crystal

In my design I am using a quartz crystal of 22.1184MHz. The design is
supposed to restrict electro-magnetic emissions at a lowest possible
level. What are the necessary guidelines that I need to follow while
routing so that emissions due to Crystal can be substantially reduced.
Would grounding the body of Crystal suffice or I need to include
separate Power and Ground Planes in my design to minimize the 3rd, 5th
and 7th harmonics generated due to this crystal ?.
